It's understandable that you would be confused. There are a few issues: 1) People are going to make claims without backing it up with proof, 2) People make blanket statements, when the reality is that certain games favor certain hardware, 3) People make a few FPS advantage seem like a "win", when it usually falls within the margin of error and makes no difference in terms of performance.
Your best bet it to always do your own research using the many review websites and don't always believe everything reported by random anonymous posters on a public forum.
The correct answer is they are both essentially the same in performance overall. Depending on which games you intend to play, one will perform better than the other.The GTX 670 will perform better in your preferred game-types (BF3, GTA IV, open world games like Skyrim and Fallout 3). It's also considerably quieter, and allows gaming with PhysX and Adaptive VSync.
