I am thinking about buying a Sapphire Vapor-x 7970 3GB and I hope to overclock it as well. I have no plans of tweaking voltage on the GPU.
Is my PSU enough to handle an overclocked i5 2500K and this sapphire vapor-x 7970? If not then I will have to settle with 7950 as I can't afford a new PSU along with a 7970.
