TechSpot's review of Borderlands 2 performance on the PC
http://www.techspot.com/review/577-borderlands-2-performance/
Here are the cliff's notes:
(1) Nvidia runs better in this game (no surprise, as they were very involved in the production of it). This is most evident at 2560x1600.
(2) It's a very CPU-bottlenecked game (EDIT: as others have pointed, out, it's actually CPU-limited) - at 1680, the top 10 cards all exhibit about the same fps on a 3770k, and even at 1920, there's very little differentiation at the top. It responds linearly to CPU overclocks - that's almost unheard of in modern games.
(3) AMD CPUs do not do well...ouch.
(4) The HD7850 is underperforming the HD5870. AMD has more work to do in getting the most performance out of that card.
(5) The 660Ti performs almost exactly like a 670, whereas the 680 is able to pull away. Clearly this game doesn't depend on memory bandwidth at all.
UPDATE: It appears that TechSpot has erroneously tested PhysX on AMD cards using the CPU, which defaults to low settings. There is no way to run PhysX directly on an AMD card, and there is no way to run high PhysX on a CPU without significantly compromised performance.
