Stuck for choice

Hi guys. Tomorrow i should be ordering a new graphics card as my friend is buying my current one off me (Hd 6870).

However im currently stuck between two choices, the hd 7950 or gtx 670.

Hd 7950's

GTX 670

Now i know that between the two the 670 is faster but i have seen some benchmarks showing that the hd 7950 has caught up in performance with the most recent 12.7 drivers.

Which would give me the best fps at 1080p with games such battlefield 3, crysis, ARMA II etc?

Is it worth getting the 7950 considering it has the better cooler and is approximately £20? Or spend the extra money and get the 670?

Cheers for your input.
