Studying the 2009 CPU chart I've come to this conclusion: Phenom II X2 550 best in games, but worst in everything else, AMD Athlon II X4 620 best in everything else, middle in games, while AMD Phenom X4 9650 is in the middle in everything else but worst in games. (by everything else I mean 3dmark,pcmark,adobe,sandra,archiving,video editing etc). I'm leaning toward Phenom II X2 550 because it's cheaper (at the moment because AMD Athlon II X4 620 is still very new) and it's Black Edition.
