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.
