So for anyone that has some old AM2 motherboard that at least supports X2 6000+ 125w, and hopefully has that "ganged mode" option, phenom 2 is a great upgrade. I wouldn't recommend the black 940 for use on those motherboards though as you can't get so great overclocks. I think a p2 920 will easily reach 3.2ghz without multiplier and from my experience this was the max stable oc on my budget board.
