I have a question for you all. Before I buy the game, I would like to know what type of FPS I would see with my system. I feel like having the smoothest possible gameplay will definitely help out my experience in the game.

My system is as follows:

Intel Core 2 Duo CPU T6400 @ 2.00 GHz (x2)
ATI Mobility Radeon HD 4570
TOSHIBA MK3255GSX ATA HD with 320 GB storage space

If I could get an opinion on this I would greatly appreciate it.
