EQ2 DOES have EAX2 and Dolby Surround support although I don't feel it's especially important myself. Having said that go for a Radeon Crossfire Board and it's definatly a non-issue as the sound on those boards is considerably better than any other mobo out. Not up to £100+ sound card standards but not far behuind and more than enough for use in EQ2 or any game TBH.
