your problem is you think the power circuitry is limited. it's not. gtx 590 is the most power consuming pci card ever sold, even BEFORE you overclock it and make it explode.
Somebody once said you could put lipstick on a pig

Anyway the Fermi in it's 500 series guise is not that bad I just think in hindsight nVidia chose a cost effective VRM solution as opposed to a high quality and rather expensive one.

Would it have also been easier for nVidia to have put 2 570's on one GPU as opposed to 2 580's?

Even 2 2GB 560's clocked well would be a very good dual GPU solution.

Like some people have suggested in this thread, perhaps nVidia were surprised by how aggresive ATi were with the 6990 and had to raise clocks from 575 or 550Mhz at the last minute. (or even unlock pipes? from 480 to 512?)
