I am building a pair of dual Opteron machines and need some recommendations on Dual Opteron MB's. The boards seem to be all over the map feature-wise (who the hell still uses USB 1.1 on some of their boards?? Tyan, that's who!) Tyan seems to make most of the available boards, but I'm not totally impressed with their features. While these machines will mostly be used for running VM's, I also plan to hijack them for the occasional bout of gaming or video work (not their primary focus however). Any suggestions?
