Best/ideal sound card to use with Roccat Kave 5.1 USB headphones ?

Hi I am after a sound card for 100% gaming only. It cant be a creative card tho as dont want to use them any more.

I will be using it with some Roccat Kave heaphones which connect via USB.

Can you recommend any ?

Do sound cards have any bearing on audio transmitted over USB ?

afaict the USB is only for power and the headphones actually use 4 3.5mm jacks to carry the sound signal. In which case any 5.1 soundcard should do it - or just use your motherboard's onboard sound (which should be more than acceptable for gaming, frankly).

Not sure... The Roccat kave headphones have 5 pins which I am guessing you can attach to your sound card for 5.1.
