Yes.

2 GTX 560 Ti 448 > 2 GTX 560 Ti 384 > 1 GTX 580

750W will be enough for any of those setups. Even SLI 580s should be fine with a 750W, provided limited GPU overclocking.

depending on what the rest of your system is like. maybe yes, maybe no. If you plan on doing some heavy oc-ing or your cpu is oc'd heavily, you may want to evaluate going slightly higher. I just purchased 2 of the msi cards reviewed in that link and err'd on the side of safety and replaced my 750w psu with an 850w, but my i-5 is also at 4.8ghz and I have pushed these puppies to 935/2100 so I'm glad I did.

According to Phaedrus' PSU calculator, a Nehalem Corei7 and a pair of 560ti's would pull 700watts. As long as your HDD's and other peripherals aren't extreme, you should be good to go! thumb.gif
