I have the same setup. Game Zero and Sound Blaster ZX. It's awesome.
Don't bother with 5.1 or 7.1 headphones, it's a gimmick. They can't do anything stereo cans can't do, since you only have 2 ears.
Analog 5.1 headphones aren't a gimmick. I have a pair and you're welcome to try. USB 5.1/7.1 is more gimmicky but even that has value because it does increase the sense of surround sound when you're in a game. I mean, sure you have 2 ears, but you can still clearly tell the direction a sound is coming from, so why would it be different in headphones?
