Ok, so here's the issue. I do a fair amount of SC2/Mafia II/Waiting for Batman GOTY ed to go on sale/and FPS gaming on the PC, and recently hooked my 360 up to one of my computer monitors and I am enjoying Halo Reach at the moment. I have a Sound Blaster Fatal1ty Sound Xi-Fi Titanium Sound card, on a Gigabyte- X58A-UD5 motherboard, i7 920(3.6ghz). I am doing this primarily because I broke the desktop mic I was using, and had to ninja my wifes for the time being, and I'd like a new headset that has an attached micro Option A, Go with existing hardware, and get; Creative-Labs-HS-980-Fatal1ty-Professional Option B, Go with the newly reviewed Corsair HS1; http://www.legitreviews.com/article/1416/1/ http://gizmodo.com/5629748/corsairs-hs1-usb-gaming-headset-is-comfortable http://www.bit-tech.net/hardware/peripherals/2010/09/11/corsair-hs1-review/1 However, my question is could I sell my existing sound card, since it would be using USB instead of 35mm connections. Or would I still need the Sound Card to drive and manage sound output? I am fairly certain I could get rid of the sound card and use the on board, but I am worried about the...Buzzing sound that might come along with it. Any ideas?
