Important question about GPU's!

[AlexAndr]

Well, I am making new build from scratch and now stuck at choosing GPU. My opponentns are:

GTX660Ti Windforce: http://www.scan.co.uk/products/2gb-gigabyte-gtx-660-ti-windforce-2x-28nm-pcie-30-6008mhz-gddr5-gpu-941mhz-boost-1019mhz-cores-1344-

Sapphire HD7950 Vapour-X: http://www.overclockers.co.uk/showproduct.php?prodid=GX-304-SP&tool=3

I heard that at low resolutions GTX 660Ti owns HD7950 by 10-15% in frame rates. I am gaming at my max 1280x1024. Thinking of playing Battlefield 3 and Borderlands 2. Also I use Cinema 4D to make 3d models and rendering.

Also I may OC. Heard that GTX 660Ti has voltage locked and problematic at OC.

Shares your ideas and give your opinions. Thank you.

P.S Combining Intel CPU with AMD gpu, will it affect performance?

I am not planing to OC as long as I am satisfied with GPU performance. Also why do I need 650W supply. I think its too much, 550W should be enough?

The Samsung Spinpoint F3 you've chosen has a miserable 1 year warranty. I'd choose a WD Black; more expensive but they've kept five year warranties (on most models) while others have cut theirs.
