Probably a 850W unit. However, there's seriously no point making a thread like this when you have Phaedrus' calculator and the recommended PSU list. Just cross-reference those threads and you'll be on the right track.

Well, with the 5** series you got more performance per watt, so I would guess Nvidia will continue the pattern with their new cards. Unless you're planning on getting two dual-GPU cards, I dare say a 850W PSU will be plenty.

I'd go 850W

I think it's a reasonable expectation that a 850W PSU will be enough for any dual card setup in the future. I strongly believe that video card power consumption has reached its peak and will never go higher.
That said, I wouldn't buy anything until the new cards actually come out, that's just a bad idea.
