I decided to do a mild upgrade and take my 2600 barton to a 64 3700, but since I'm keeping my AGP video card (X800xt) I decided to go the cheaper route of socket 754 (I'll upgrade to PCIE and 939 later). Looking at reviews, no one seems to mention the quality of onboard audio though. Right now I have an Nforce2 which has great onboard audio but I've heard the more recent Nforce boards are actually worse. After dealing with a nightmare of compatibility issues and driver conflicts with an SB Live (bah on Creative) I don't really have much enthuisasm for another sound card either. Anyone know if any of these boards have exceptional audio?
