Well, the 280X has a 250W TDP, two of them would then be around 500W TDP only for GPU, then of course they would be overclocked, in the same system as an overclocked CPU a couple of HDDs and so on. I think it >should< work, but I'm just not at all sure about that![]()
Cards only ever hit their TDP when using heavy stress benchmark software.. a 750watt PSU could most likely run light overclocked Xfire 290x's.

Edit: also check this out, apparently its released today, which means, the NDA is near its end!

This goes along with rumors. I'll wait to see what the 290 has to offer though. Spec wise it's between a 780/titan so we'll see how the price plays out.
