Have you considered the possibility of the copy of the game you have right now functioning poorly? I've had copies of games I play that would function particularly poorly but switch to the EU disk / US disk vice versa and have better performance.

I presume you also have a clean CPU that isn't being clogged by unnecessary apps running in the background? (In task manager how much of its being used before game is run?)
