sound card

If your current motherboard on your desktop PC has a bad sounding onboard sound, using a seperate PCI sound card can improve the sound quality. The sound cards' sound processor unit may help make your games run a few frames faster because the sound card has its own sound processing chip and RAM...

When I build a Gaming PC, or a Home Theater PC for mainly watching videos like movies, and music, I would want to buy a higher quality sound card which has better sound processing capabilities, and specs.
