I'm in the same boat. I just bought a pair of Sennheiser HD 598's and I'm looking at getting a good soundcard to go with it. I mostly game on the machine, but I usually listen to music when I do. I'm not an audiophile by any means, but want something that my new headphones can take advantage of! I've narrowed down the card I want to either the Pheobus or Essense STX
Can anyone provide us with any advice?
