If you do find either on a cheap, just make sure they're made with the GTX 580 or GTX 680 PCBs, since the stock PCBs for both of those GPUs are rather lacking.
GTX 570's stock PCB being worse. You can do a quick google on that one to see some of the horror stories.

Research, mostly into the power draw of individual components, or at least whole systems when efficiency is taken into account.
TechPowerUP!, Xbit Labs, and a few others (English & non-English alike) have these results at the ready, you just need to search for them.
Like wise, just because everyone throws up a figure about total system draw doesn't mean it's accurate.
Most important things to look for is their testing methodology as well as their test system. So you can know what their power meter is, as well as how efficient the PSU they are using, is.
Though, some sites break down by individual components which is much better.
If you don't want to worry about that nonsense, you can always download the PSU Calc linked in the top of this section and just input the system info.
