A good power supply for this build?

Get a 800w PSU, Seasonic, XFX and most Corsair are good, just check the reviews beforehand, depends wherever you want to spend extra and get modular or not really.

Why not just buy a GTX 670?

Because looking at benchmarks 2 gtx 660s beats a gtx 680. Isn't 800watts to much?
 
I'd go with 700 or 750 to be very safe.

Also, keep something in mind... the 660s are only better in games that support SLI. Most of the games that are badly optimized and thus have bad performance? Aren't going to support SLI. The general consensus is to not ever sli low-end cards, because when you can't use them, you're running on a low end card.

Yes. They have better oomph. But graphics cards are about SO much more than raw oomph.

GTX 670 is so much money, losing at benchmarks bf3, skyrm, max Payne Ect all support SLI and are double the fps nearly with these gtx 660s. Nvidia I think now are really good adding support for SLI in games.
 
Not for much more fps, the 670 can be bought with less money, when certain recent games that will not support sli the 670 will be better, besides the sli setup is more for 1200p gaming, you probably will play at 1080p.
If you want latter on you can sli the 670.

PSU's lose their ability to generate their rated wattage over time. Get usually about 100 watts more then what you think is enough for. Who cares about an extra .30 cents a month on a bill. It will keep your computer going longer then one recommended one now.
