Long story short, I was given a g35 headset for christmas, and the headset feels great but it is USB connected and I already have a good sound card. From what I've been reading I guess the usb bypasses the sound card? My question is are sound cards not really valuable anymore? Should I just stick to a usb headset or go for a sound card and a headset that plugs into it? I might take the g35 back since I have an Xfi Gamer sound card, so suggestions for a new headset would be appreciated. Thanks.
