[joasjoas]

I have been reading several post, but I have not yet reached conclusion.
My use is for gaming, I have a xonar dgx, game to all kinds of games, lately fps, wow, lol, etc ...
At first my idea was FX Hi-Fi X6, but I do not know if this is the right thing to do, or just look for an amplifier and use my sound card from dac, help

xonar dxg is a pretty good card, unless youre really going to spend a lot of money on a sound setup, i would keep the xonar.
