I'm building a new PC and I though I've earned myself a nice sound card after using on board audio on all of my builds. I'm split between the sound blaster and the xonar dx. Both are advertised for 7.1 surround and gaming. I'll be using the card for watching movies, videos, listening to music, and lots of gaming but only on a pare of stereo headphones, nothing else. I just want the one that has crisper audio, more amplified sound, and best 3d sound. Also good driver support would be nice. Any help will be greatly appreciated!
