I currently have the following setup:

CPU: Core i5 3.4Ghz 3570
RAM: Corsair Vengeance 8GB 1333Mhz
GPU: Powercolor 7950 3GB
PSU: 750 Watts

I would like to find out what GPU I can get, that won't be bottle-necked by my CPU. I was looking at a MSI 780 Ti OC, but I have heard that my CPU is way to low to fully experience the card.

Any suggestions?
