Which PSU at 750 Watt are you planning to buy? The Setup looks cool, but don't safe money on PSU, cause it will blow up your card/cards...

But right now I would say Single 7950. Then you will be able to take another one later on, if needed. Instead of replacing both cards.

Single 7950 for sure, always go with new tech. 700 watt psu is more than enough, single rail is best
