Just FYI ... A little reference data, from a recent thread, that may interest you ...
... This is all "pasted in" ... in chunks .. so ... might make sense ... might not.

Scroll way down and look at the comparison ...
Altho WE are currently discussing the Propus 940 vs. the 965BE .... I have chosen to benchmark the Propus 945 against the 955 (because the NON OC'd Timings are MUCH MORE INDICATIVE of the true (OC results) ...
... FYI ... The 955 clocks just as well (identically) to the 965, using the Hyper-212+ (vast majority of individual cases) ... Likewise ... A propus 640 should clock to ~3.6GHz (stable) ... Higher than a stock 645) ... And a 635 would even be fine, but the 640 is guaranteed @3GHz, on standard clock/cooling, which would be enough (by it's self) for a decent fps frame rate. (at only $99).

There are a few gaming titles out there that will take advantage of a fourth CPU core---real-time strategy games, mostly--making the Athlon II X4 a potentially attractive choice to enthusiasts who multitask while they play, and are willing to overclock this processor. Moreover, as a general-purpose CPU (during the hours you don't spend gaming), the quad-core solution is going to be superior. Now found as low as $100, this CPU is well within the grasp of the budget-oriented gamer.

Pulled this from the first article:
There are minor loses in gaming performance along the lines of a 1-10FPS drop compared to the Phenom IIs and other quads with larger cache sizes but at the same clocks in many well threaded programs such as Handbrake the Athlon IIs should be equal their more expensive Phenom brothers.
1 to 10 variable FPS for another $60? I dunno man... Just doesn't seem like a big deal to me. For 5 FPS, I would rather wait till I upgrade to the next processor generation. Besides, I'm building this for RIFT mostly (MMORPG) - I think it is a well threaded program?
