Should I get EVGA GTX 670 FTW or 7970 OC with a Boost?

[HostileSnack]

Should I get the EVGA GTX 670 FTW or the Sapphire Radeon HD 7970 OC with a Boost 3GB ? Which one will deliver me the best performance in high end games like BF3 , Guild Wars 2, Skyrim , DmC etc..
My rig:
CPU : intel i5 3450 3.1ghz turbo boost 3.5ghz
GPU : HIS 7770 ghz edition GDDR5
MOBO: Intel B75 Express Chipset
PSU:Corsair Builder Series CX 600 Watt ATX/EPS 80 PLUS (CX600)

Monitor is 1600x900

At 1600x900, both are complete overkill. Those two GPUs are best suited for 1080p+. At your resolution, consider an HD 7850 or HD 7870. Both are very capable mid-range GPUs that will handle games great @ 1600x900, and even handle games fairly well at 1080p.

The 7970 is so much better when overclocked. Easily beats out the 680.
