To check your processor, do the following:
In the run command, type in dxdiag.
Under the system tab, look for the processor under system information.
That card that you mentioned is good. Good find.

I know someone who has that card, and it runs at 40fps with a dual core processor. maxed out with the crowd at medium.
That card is right for you, and it is good that it is under the power unit.
