You mean sound card, the link above is a Audigy SE its a software based card, it will sound better than onboard but it doesnt free up any CPU time. For that you need a hardware based card, something like the link below or better http://www.newegg.com/Product/Product.aspx?Item=N82E16829102007
i have a sound card right now, not that great, some off brand, bc my onboard didnt work with VISTA. soo i know getn an onboard is better , but what makes one better than another ????
i just know x-fi is the best and sound blasters are cheaper but decent and i want to point out that you have a crappy videocard as i rma mine : P i had a x1650pro gamer edition superclocked it was the worst card i ever had it was probably same as my geforce 7300
