I got around 200$ to spend and plan on upgrading my old G4ME Zero's. I know that the 6xx will work on my audio card (Xonar DGX), but bass will be a bit thin. I would like to know what would be better for gaming and casual listening. Games would be CSGO, R6S, and Pubg.

The Xonar DGX's headphone amplifier is too weak for driving the 300-Ohm HD6XX headphones.
A $200 Audio Technica (40-Ohm) headphone would be a better match for use with the Xonar DGX.

I have both and I personally think you would be overall better off with the HD6XX. That said, you should invest in an amp if you want to get the most out of it. The DGX will not drive the 300 ohm HD6XX optimally.

For the price the choice is obvious, HD 6XX.

For gaming (and ease to drive) I'd look into a used Fidelio X1/X2,which will provide big bass and wide sound stage for gaming,its comfortable,and easy to drive from your soundcard.
