[Prisoner]

I just bought the G4ME ZERO ,my old headphone is the hyper x cloud 1 but i feel my old headphone sounds was better and louder , i ask my friends and it's about my montherboard can't fully drive the G4ME ZERO so i should buy a sound card , but i never own the sound card before , i decided to buy a ASUS Xonar DGX , but i heard that Soundblaster Z are better
