Atm I have a siberia V2 stereo headset. I have been looking at some 7.1, 5.1 and 3D headsets. I read on some forum where some claimed that 7.1s and lower was fake and there wasn't really any difference. And if I were to go for any of this three types of headsets which should I choose, 7.1 - 5.1 or 3D?
