Choosing between the 670 FTW and 680

im getting a new video card to replace the one that i have already im choosing between the evga 670 FTW and the evga 680 referance, which do you guys think is better the two i have found are more or less the same price. thanks

Note: i will be using for surround and 3d not necessarily at the same time

I'd get a 670 since it's a bit cheaper usually and it performs equally (Usually) to the 680 in gaming benchmarks and has a similar amount of CUDA Cores.

The 680 if you can afford it. typically the 680 is the pinnacle of pseudo affordable single GPU cards (because I don't consider the Titan as a standard single GPU card, if not simply because of the price tag.)
