Cool thanks. I'm running a EVGA 780i and Corsair TX850 power supply so I think I should be ok just wanted to know if it was possible. Hope it has a decent performance gain. If not I'll just sell my 8800GT to a friend.
The only time you might see any gains is in a game that actually uses GPU
PhysX, if you don't play any of those games then it won't do squat for overall performance.
