Will the game run on a GHZ between 2.0 and 2.4?

Yeah, but the kind of cpu is more important.

Well I'm running on an AMD Athelonx2

Or an Intel Core 2 with: ATI Mobility Radeon HD 4570 with 512 MB discrete graphics for up to 2280 MB of dynamically shared memory allocated by the system

Will be fine. Frequency only matters within the same line/model of CPUs. The min requirements ask for a Pentium 4 @ 2.4 GHz. Either of your chips will surpass that. The question is video card...and a Radeon 4570 will be enough for mediumish.

You need to keep all these questions to one thread please.
