Its a cheaper setup Chankama I believe, so any half decent sound card would probolly do for it. If you could find some of the older turtle beach cards it would do fine, as well as the newer turtle beach ones or the cheap soundblasters, the like 30$ ones, forgot the name.
I am not a big expert in PC audio, as i focus in the pro audio industry.
I was just thinking, a soundcard with Sharc DSP's like my cd player. That thing would be really expensive though
