Wait, now two different people posting in the same thread - confusing.
iamkain - could you post the rest of the PC specs and what you have recently changed.
will - The problem with the 3200 is that it (usually) has no dedicated ram. That will severely limit the capabilities of the computer in gaming. You may be able to get playable framerates on it (I could on my 3200 and Rome, which is a similar engine) however you will have to turn down graphics a lot. Do you already have the game and are wondering whether to install, or wondering which computer to buy, or wondering whether to buy the game?
