5970 probably, particularly if you use 3 of them on one board.

Depends on how many you can run on one board. I'm running 8 5870's on one board generating 1550 Watts @ 3.2GHs, that's 2.06 H/Watts.

You dont even need that. PCI-E 1x is enough, all you need is a cable to convert from the 1x slot on the motherboard to the physical 16x connector of the card. It will only work at 1x speeds obviously, but PCI-E lane width is not an issue for bitcoin mining.

You are correct, one of my cards is actually on a 1x - 16x. This board has the most slots outright that I have seen though.
