People dont buy sound cards because it helps out there cpu, they buy it because they sound much better and have more features. Thats like saying, "who need a video card when you can just use integrated."
Lol, oh man, I bought the X-Fi Xtreme Music card, the difference is incredible. And yes, I guess it helps out the speed too, and to me if i could scratch out 5% more speed somewhere, I'd do it without hesitation. So no matter how you look at it, a sound card to me is a must.
