sound card - up to you. if you want to have perfect sound, two-three extra fps, and an advantage in all games especially bf, cod, cs and all shooters /you know, knowing exactly where your enemy is and hearing perfectly what is he up to across the map is awesome/, you should get one.
also, you definitely need one if you plan to spend more than 20$ on your audio /and not planing to buy overpriced usb headphones/
