Ya it'll play games well.
The Core i5, and Core i7 don't have much of an advantage in games anyways, same applies if you compare the PII to the Core i series to even the AII X4's. The difference will be a couple FPS at the most, and that's at normal resolutions; if we're talking like at 640x480, there's no doubt it'll be a lot higher on those processors, but it'll be negligible still because your FPS will already be high anyways.
