So my power supply is holding it back.
Will need to wait a while to get a better one.
Just noticed this part, lol.
I'm using a Corsair HX750W with 2 EVGA GTX260's in SLI and it barely breaks a sweat even with my overclock on the CPU. There not cheap, It's $149 at newegg:
the HX620W also has great reviews on the net, $119 at newegg:
Both have a 7 year warranty (manufactured by Seasonic) and are modular. I have used these in more than a few builds for friends also and no problems have ever surfaced. Like I said though, they're not a cheap solution, just a good one.
Corsair also has the new VX series, non modular, 5 yr warranty(manufactured by CTW), 80+ efficiiency rating and out of stock, lol. Looks like they only go to 550W anyway, I just did a build for a friend using one of these and they are pretty solid, it was $89 at the time.
Hope that helps.
