Help with graphic cards

[tommip1]

I'm building my own PC and I need some help with what graphics card should I get.

Sapphire ATI PCX HD 7970 3GB
Gigabyte PCX GeForce GTX770 4GB Overclock
Gigabyte PCX GeForce GTX770 2GB Overclock
Gigabyte PCX GeForce GTX670 2GB Overclock

The prices are very similar so I don't mind paying a bit more for the better one but it's still nice to save some money If I can

HD7950 is the best deal. I'd recommend either going with that or stretching your budget for an GTX780 as the next step up.
