Ok, I know that the 7970 would run faster, but I heard that it's a waste if you're using only 1 monitor and a resolution under 1080p?, it also overclock better than the gtx 670, which I'm not going to, well maybe a little but not like crazy, price range about the same(ish) I can rebate the gtx 670 with $20 back.

CPU: i5 3570k
