The PSU requirements are not out of line with modern high end cards. The GTX280 launched with a 550w/40a requirement.
As far as it's efficiency, it's over 2X faster than the GTX280 at GPGPU, upto 2.3 faster than GTX280 at 8X AA.
It's 80% faster than a GTX285 at Dark Void at 19X12 with AA on and medium physX. It's 65-70% faster than a GTX285 at FC2 with 4XAA at 19X12 or 25X16.
A 5870 is more power efficient, but my guess is most people buying GTX480s will already have a 600W psu or higher. Can't remember when I switched to 1000W PSUs, and I've been on 1200s for almost 3 yearss I believe.
Some people might consider the GTX480s for the additional things they offer like PhysX, CUDA, 3D Vision, 3D Surround, better multi GPU drivers, and better AA in UE3 apps.

As for the above performance numbers, they mean squat until an independent review is done.

I am glad that both companies will have DirectX 11 cards by the end of it. I want more companies to take advantage of those awesome DirectX 11 features like Tessellation and any additional features for DirectX 11 cards in Direct Compute. As for the performance of the GTX 480, that's still a mystery. As DeusEx (awesome game, by the way ) has said, we need to see benchmarks from independent websites to get a clear picture on performance. I would love to check the performance first-hand if anyone from Nvidia would be willing to send over a card .
