You can play the game.
The software that is checking to see if you are capable to play it, is simply checking your current CPU clock speed.
As mentioned with CnQ on, during times of non intensive load the CPU underclocks itself. So the program that is checking the requirements is looking at a the speed that CnQ has not the speed of the CPU once its is under load.
Once your CPU is underload (from a game, or ripping a DVD etc) is goes back to the normal 3.2Ghz that it is rated at.
