before u ask which one is good for gaming, ask urself what type of gaming.
if u want to play single player storyline games, RTS, etc etc...then there are of cos better choices out there than barracuda, 5hv2 etc.
but like for competitive FPS...where u need to hear stuff like footsteps clearer and more accurately without too much bass disturbing...then thats where the so-called *lower quality* of headsets like 5hv2 and barracuda comes in.
then those sets like siberia, megalodon are like jacks of all trades.

Oohhh okay.... With the addition of USB Soundcard, will it increase the sound quality output of the headset?? Errr maybe from 2.1 become 5.1?? Is it possible?? Hahaha, sorry for asking silly questions like these... I don't really know much about it!! Thanks in advance!!
