For a build with a single GTX580 a good 650W PSU will be enough.

If you want to SLI them then you will need 850W and up.

The 580 is way too expensive for what it offers, better get a HD 6970. The factory overclocked ones are very close to the 580.

If you can crossfire/SLI, the future-proof factor is already there. CF/SLI scaling beyond 3 cards is pretty dismal, so 2 6990s might not be much better than 2 6970s.
