Any of the Phenom II's will run it - but the higher clock speeds and cores will obviously run it better. if the 955 is your upper limit - and you haven't bought a vid card as yet (the 4200 is a low end graphics card and being "onboard" can cause issues - it has only 128Mb's dedicated and SH5 requires 512 Mbs. System memory MAY make up the difference - but it may not...) - I would have to ask what your willing to spend on the graphics before I could recommend a chip. The reason here is not that I am nosy - its because with the numbers we can figure out the right balance so that neither device "bottlenecks" you in games.

Regardless of which you choose - stick with a quad core. The boost from it long term as well as short makes it worth it. Without knowing your budget - a 925, 945 or the 955 are all solid choices. Avoid the 600 series - as they are all non-Phenom II's. Also - make sure you get the 95W version of the chip (as the 945 and above also come in 125W flavors which your board won't support). Difference between a 95W 925 and 925 is 20 bucks on Newegg, but both are solid. If I had a very limited budget, I would go with the 925 and use the extra to be added to the vid card purchase to make sure I don't get shorted on that side.
