I think you should leave the Thuban cpus and go for Sandy bridge i5.They offer more performance.

650w or 750 ???

The Cooler Master GX series is disappointing to say the least, it has excessive ripple on the minor rails once over half load, i would stay clear of it. They are usually a similar price to good units from Corsair, Antec, XFX, and Seasonic. A good 650W can handle 2 6870s, that GX 650 is not good though, if you only intend to run a single card you can get a good 550W unit.

forget cooler master, they arent very good value for money and rarely are able to produce their rated power, exception is their very high end models. +1 to hunter , corsair, antec, xfx, seasonic is what you should look at.

what about a Corsair Enthusiast Series 650-Watt ?
