Any more opinions?

  The Audio-Technica AD700x is not really available or ridiculously expensive (from 250 $ up) here in Germany. Other possible options for me are AKG K612 Pro, AKG K701 or Beyerdynamic DT990. What are the best alternatives for FPS gaming?  Thanks

Hi, I just ordered a new gaming pc with Asus Xonar DGX sound card. As I'm going to play first person shooters most of the time, I want to buy the Audio-Technica AD700x. Is the Asus Xonar DGX sound card a good configuration for this headphone or can you recommend a better one?   Thanks and...
