in gaming, there won't be much of a difference. your 4400x2 at 3ghz is probably faster than a 9500 at 2.2ghz, and the 9500 won't oc worth a crap on an am2 board, not that it would do much better with am2+. You'd be lucky to get 2.6ghz, more likely somethign like 2.4, so it won't really be an upgrade if all you're concerned with is gaming performance.
