Computer video card buying tips

Computer video card buying tips

With the popularity of computer gaming video cards are becoming the most commonly upgraded components in a computer. However, purchasing a computer video card can sometimes be a very confusing and frustrating task. Before purchasing a video card, keep the below recommendations in mind.

Connection

Today, there are three bus (slots) a video card is capable of connecting to. Although with most modern computers today it'll be either PCI-E or AGP. Before buying a new video card make sure you get a video card that will be compatible with the available slots in your computer.
PCI-E or PCI-Express was approved as a standard on July 2002 and is the latest computer bus found in computers. PCI Express is designed to replace PCI and AGP and is available in different formats: x1, x2, x4, x8, x12, x16, and x32. See the PCI Express definition for a full description and related links.
PCI express x16 slot
AGP or Advanced Graphics Port, is a new standard available on Pentium II and later motherboards. Introduced in 1997, AGP is a 32-bit Bus designed for high demanding video cards. AGP has a direct line to the computer memory, which allows 3-D elements to be stored in the system memory instead of the video memory and is available in three different standards (1.0, 2.0, and 3.0). See the AGP definition for a full description and related links.
AGP slot
PCI or Peripheral Component Interconnect, was first introduced in 1992. Although still in use today, most computers today use AGP or a PCI-E slot instead of PCI. See the PCI definition for a full description and related links.

Power supply

Today's video cards are one of the must power hungry devices in your computer. Make sure that your power supply meets the requirements of your video card. Many video cards will require a 500W or more power supply. If your computer doesn't meet the power requirements you'd need to upgrade the power supply before being able to install the new video card.

Memory

Another important consideration when purchasing a video card is the amount of video memory the card has. Like system memory, the more memory located on the computer video card in most cases the greater capability of the video card. Today, we suggest at the minimum a video card with 256MB of video memory.

Other considerations

Below are some additional considerations you may want to think about when buying a video card.
Ports - Many newer video cards only have a DVI connection or both a VGA and DVI connection. If you're using a video card with a monitor that has a VGA connector it can still be used, but you'll need to also purchase a DVI to VGA converter if not included with your video card.
Chipset - There are dozens of different video card manufacturers. However, there are only two major chipset manufacturers; Nvidia and ATI. Although both are great manufacturers there can be great big differences between the two as far as performance. Before buying any video card it's a good idea to look up a hardware review on the video card before purchasing it if you're concerned about it's performance.
Size - If you have a smaller computer case fitting some of the new video cards in the computer many not be possible. Video cards today are much larger than older video cards because of their increased capabilities and need for cooling fans. Make sure your case is going to have room for a new video card. The only way to do this is to open the case and physically look.
Warranty - How long is the warranty and what does it cover.
Support - Is the technical support number a free number and is it open 24 hours, 7 days a week? You can find contact information for all major video card manufacturers on our video card contacts page.

Price range

The price range can vary depending on the brand of video card, amount of memory, the interface used, and other available options. In general, prices can range from $100 to $1,000 USD.

Computer software utility buying tips

Computer software utility buying tips

There are some consideration to make before purchasing any computer software utility. Below is a list of considerations to make when buying any utility for your computer.

Documentation

Documentation is an important consideration when looking at a utility program that you may be unfamiliar with. While many utilities such as a virus protection program may only require very little documentation, other utilities such as backup software or other involved software may require more documentation because of the complexity and available options provided by that software.

Hardware

When purchasing a program that relies or requires hardware, such as a backup utility, ensure that you meet the hardware requirements or your hardware is compatible with the software. For example, not all backup utilities are compatible with all backup tape drives.

Operating System

Utilities such as a virus protection program or crash protection utility are very dependent on the operating system. If you have Windows 7, make sure you purchase a program that is designed for Windows 7. If a program is purchased that is not designed for the operating system you are using, you may experience problems unless updates are available.

Support

Verify that the developer of the software utility you are purchasing from has the needed support. Complex utilities such as a tape backup software may require help from a support staff.

Updates

Many utilities require updates; before installing or running the utility on your computer, ensure that all updates have been obtained from the software developer first to prevent possible corruption or data loss.

Warranty

While not all companies provide this option, see if the company provides any warranty program if software is to become lost, corrupted or bad because of the utility being run.

When looking at the USB device, ensure that you meet the system requirements. Many USB devices today require at least Windows 98 or higher.

Computer speaker buying tips

Computer speaker buying tips

When compared to other computer hardware, purchasing speakers for your computer can be a fairly easy task. Below we have listed some things to look for when purchasing computer speakers.

Subwoofer

For most users a standard pair of computer speakers will suffice. In some cases it is recommended, that if you would like extended bass, that a subwoofer be purchased with the pair of speakers.

3D-sound

If you have a sound card that is capable of 3D-Sound and you are a computer gamer, you may want to consider getting a four, five or six speaker setup.

Power

Today, a standard power cord powers most speakers. However, there are still speakers available that are powered by batteries and USB. If you want something other than a power cord make sure you get what you want.

Appearance

While not thought of as important by many, you may also want to consider the appearance of the speakers. How are the speakers going to position on your desk or monitor? Are the speakers going to fit on your desk, or are they going to be too big? If you have a subwoofer, is it going to be able to be placed on the floor or behind your desk?

Other considerations

Some additional considerations when purchasing speakers include:
Warranty How long is the warranty and what does it cover.
Support Is the technical support number a free number; is it open 24 hours, 7 days a week.

Computer sound card buying tips

Computer sound card buying tips

When purchasing a sound card, there are several factors that can complicate and sometimes not allow you to install your sound card. Before purchasing a sound card, it is important to take the below things into consideration.

Interface

Ensure that you have the available connection on the computer. Sound cards are available as both PCI and ISA.
PCI - Today, most cards available are PCI; if you plan on using your sound card for such things as playing games and watching DVD movies, it is recommended you at least get a PCI sound card.
ISA - Today, ISA cards are relatively cheap sound cards, which allow users that may not have as much money to have sound on the computer. In addition to being a cheap sound card, purchasing an ISA sound card will keep an additional free PCI slot available.
In addition to verifying your computer has the available connections, it is also important to look to see if your computer has a sound card that is built onto the Motherboard. Verify that this sound card can be disabled or will be disabled when the new sound card is installed. Additional information about on-board audio can be found in document CH000261.

Available connections

After determining the available connection on the sound card, it is also important to look at the available connections on the card. When purchasing a sound card it is important that it has the available connections on the card.
  • Available speaker connections - For computer gamers it may be important that the card has two available speaker connections. One connection for the front speakers and the other for the rear speakers. Users who do not plan on using four speakers or utilizing this technology only needs one speaker connection to connect the set of two speakers to.
  • Midi port and Game port - The midi port allows a user to connect a Midi keyboard; however, it is more commonly used as a game port, allowing users to connect game paddles and joysticks to the card.
  • Microphone connection - Today, a standard with all sound cards, it's important to verify your sound card includes a Microphone connection

Full-duplex

Today, included with most sound cards, FullDuplex allows for sound cards playing and recording sound at the same time. This feature is most commonly used to do voice communication over the Internet or speakerphone.

3-D acceleration

Today, 3-D Acceleration is used and found in computer games. Below is a listing of the three 3-D acceleration found today.
DirectSound 3D Microsoft's DirectSound3D software API included with DirectX. When compared to other available 3D standards.
EAX Creative Labs Environmental Audio Extensions that creates very realistic and believable sound effects based in the environment of a game.
A3D Originally developed by Aureal, A3D is a software API developed for additional 3D acceleration without using Microsofts API code. Unfortunately, on June 6, 2000, Aureal went off-line because of bankruptcy.

Other considerations

Some other important considerations to look at when purchasing a computer sound card include:
Warranty How long is the warranty and what does it cover.
Support Is the technical support number a free number; is it open 24 hours, 7 days a week.

Price range

The price range can vary depending upon the sound card purchased and the available options with that sound card. Below is a listing of some examples of prices you are likely to see when purchasing a sound card.
Sound Card: $20 to $300

Server buying tips

Server buying tips

Purchasing a server for any business is a very big decision, and if not done properly, can reduce productivity or cause loss of money in the business. Below is information and help for what to look out for when purchasing a computer server. It is important to also note that every business is unique and may require more or less of what is listed below.  

New vs. Used

Purchasing a new or used server or server equipment can be a method of saving the company additional money; however, it can cause lost money if that hardware or server does not meet the company's needs. When looking at purchasing a used main server or file server for a computer network, ensure that the server is going to meet the company's needs as far as performance and reliability. Unless the perfect used solution is found, we highly recommend purchasing a new main server, file server, network server or database server, as it has the latest hardware innovations as well as have a warranty, which allows parts to be replaced or repaired within a short period of time, keeping the network up and running.
However, other servers such as a print server or hardware such as a router or firewall can be purchased as used and meet most companies' needs.

What to look for

When purchasing a server, it is important that either the company or the network administrator consider the following:
Case and rack
When looking at the case or rack, look at the expandability as well as the accessibility of hardware. Determine how may drive bays if any are available as far as what drive bays (5.25" vs. 3.5") or available hard drive bays in the computer.
Drives
Hard drive
  • The available amount of disk space on the server can be an important consideration especially if the server is going to be a file or network server. Consider the space requirements needed for the operating system, applications, tools, utilities, web pages, files, and user settings.
  • When also looking at the hard drive, it is important to look at the hard drive interface. The majority of all servers today use either SATA or SCSI hard drives.
CD-ROM
  • CD-ROM is not a critical item for most servers as it is usually only used to install additional software onto the server.
Backup
For all networks, backup is and should be an important consideration. Most companies need important data, such as company or customer related information, backed up on a daily basis. When looking at a backup solution, consider the following.
  • Is backup available with the server, if so what is it?
  • If available, what is the capacity of the medium?
  • If available, how fast is the medium (how long does it take to backup 4 gig for example).
Memory
Memory is and has always been an important consideration when looking at purchasing a server or any computer. Determine the amount of memory included in the server as well as verify if that memory can be upgraded in the future. It is recommended that at least 512MB of Memory be installed into the network or file server.
Network card
With the increase with more than one computer in the house and with broad band solutions, sometimes requiring a network card a network card is becoming an important consideration when purchasing a computer. Network cards allow users to connect to other computers and have small networks in their home or office. This allows for data transfer, file sharing, Internet connection sharing, printer sharing and other helpful uses.
Operating system
When setting up a new network verify the operating system or networking software is included with the server. If no operating system is included with the computer, verify what operating systems have been tested with the computer. For example: Novell, Windows NT, Windows 2000, Unix, Solaris, Linux, SCO... Etc.
It is also important that when setting up a network that the operating systems being installed or included is something that the network administrator is familiar with or requires for compatibility with other software.
Power
For large networks or servers, power may be an important consideration. Look at the available amount of power supplies as well as the capacity of each of the power supplies.
Additionally, if you believe power may be an issue in the future, look at the availability of upgrading or adding additional power supplies to the server.
Processor
The computer processor and the amount of processors the computer can support is one of the most important considerations when looking at a server. When looking at the server, consider the following:
  • What processor is included? (Intel Pentium, Intel Xeon, Digital or other).
  • How many processors can the server support? (2, 4, 8 or more).

Brand of computer

When looking at purchasing any brand of computer you will hear good and bad stories. Regardless if the story is good or bad, these stories are always based on the experience of that user. While it may be true that the user had a bad or terrible experience with that computer, all computer manufactures have had users who have had a bad experience and there is no such thing as a bad or perfect computer manufacturer. Below is a listing of various things to consider when purchasing a computer and in some cases how to tell the good from the bad.
Documentation
Verify if the server or networking device comes included with documentation. While most hardware, such as a router or hub, will not require documentation for most network administrators it is important that a server be included with some documentation that help with configuring the server or server components. This comes in real helpful for configuring jumpers and upgrade information.
Location
We use location as a description to describe different topics. First, what is the location of where the network hardware or server is purchased: If the network hardware or server is purchased at a local retail store, can the network hardware or server be returned if unsatisfactory or incompatible to that store? If the network hardware or server is purchased through mail order or directly through the computer manufacturer or reseller, where can the network hardware or server be returned if unsatisfactory or incompatible?
Second, can the store location of where the network hardware or server was purchased service the purchased product? If not, where is the closest location to where it can be serviced?
Third, if the network hardware or server is purchased directly from the computer manufacturer and is shipped through mail, how is it shipped? What is the time period for the network hardware or server to arrive to your destination? What happens if the network hardware or server is damaged during shipping?
Return
Verify you can get money refund for the network hardware or server. Many computer manufacturers will not refund your money but instead may offer an exchange for another product of similar qualities. Verify with the manufacturer or the reseller what their return, refund, and exchange policy is.
Service
Service is an important consideration to look at when looking to purchase a networking hardware or a server. The service is how many companies describe the repair of the device purchased if it's to become unusable. Below is a listing of some examples of services.
  1. Is the service onsite, meaning a technician will come to your location to replace or fix a bad component. If the service is onsite, is it for the complete time of the warranty? Finally, if onsite is offered because it is likely this will be a network critical component, what is the time frame for the repair to be completed and can it be done 7 days a week 24 hours a day?
  2. If onsite is not offered, what is and for how long?
  3. Are their local service centers that may stock the potentially bad part or stock parts that can be used to exchange the part that has gone bad? If yes, what are their hours and availability?
Support
Manufacturer support for most companies is an important consideration as if an issue arises with the computer you must be able to contact a support representative. Things to consider when looking at the support options of a computer are listed below.
  1. Is support open 24 hours, 7 days a week? If not, what are the hours, or is a paging service available?
  2. Is support open on holidays? If not, what days are it closed, and the days that they are closed is a paging service available?
  3. What support options are available? Phone? E-mail? Web? Chat? Pager?
Upgrade
While this option may not be considered at first when purchasing a computer, it is an important consideration. Below is a listing of different options to look for when looking to upgrade a computer.
  1. What can be upgraded in the computer? RAM? CPU? Hard Drive? Video Card? If available to upgrade, what are the maximum amounts or is it specified within documentation provided with the computer?
  2. Does the computer have on-board hardware such as an on-board Network or SCSI? If yes, can these be disabled with a jumper or through CMOS. This is important as many computer will disable the device when a new device is added. However, this does not always work and may cause future issues. Ensure it can be disabled and that it is not a device that auto-disables.
Warranty
Finally, what warranty is offered by the computer manufacturer? How long is the warranty? Does the warranty cover both hardware and software issues?
