My gtx 560 arrived today (I ended up going with nvidia because of the larger gpgpu community). The new card boosted the FPS by about 5 fps. Now the fps averages about 53. I can also play the game at higher resolutions without losing frames.
Although it didn't get me to 60 fps like I had hoped, I think I'll still be keeping the card for the CUDA capabilities.
