MB ASROCK Z77 EXTREME6 Z77 is the mobo. But it's ok I'm taking them back anyways...way too uncomfortable for the price, I do have a question tho do i need a 3.5mm headset to get good sound out of a soundcard or will a usb work? The soundcard in question is the Creative Sound Blaster Z, and the headset I'm not sure of yet.
I don't have any personal experience using USB headphones because I researched that before I bought my TurtleBeach EarForceHPA-2 5.1 headphones, that uses discrete drivers. In reviews that I had read people preferred 3.5 over USB. Also, since you have a sound card I would definitely use 3.5.
