I would avoid both. Right now, all the board manufacturers are having problems. Your best bet is the DFI board since DFI has great customer support if things go bad. Plus, the ASUS isn't even readily available. Consider the Chaintech as well, since the biggest problem is the inability to change voltage b/n 1.5-1.6 (not sure on the new revision, that will probably be the best value board available). Any suggestions from others? I am in a similar situation and the boards I reconmended are what I'm considering....
