Best way to determine OC potential?

I am looking for a new AM2 CPU and I can't decide which ones will give the best potential overclock. What usually determines overclock? Wattage? Die size? Series?

Basically, it all depends on the size of the processor, Like is it 90 NM or 65 or 45?? Because, smaller ones will required less voltage and therefore emits less heat. With less heat, you can overclock better. That is why, the intel core duo can be overclock more than the AMD athlon x2 dual core. Because intel is 65NM and AMD is 90NM.

PS (by the way, fuzzy wuzzie is a familiar name)

FUZZY is the name of my dog it sounded pretty familiar to me lmaonaise !!!

mintico is right ! well there is part of luck also... a bang for the buck (85$) would be the 4200 EE considering its not hungry in power at all and it has a pretty good potential... i run mine around 2.5ghz but ive seen some around 2.7-2.8ghz depends how lucky u get !!

lmaonaise, nice.


Anyway I suppose I should have updated this, I ended up getting a 4000+ 65W, it's running fine, up to 2.3 from 2.1 stock, mobo is limiting me after that. It runs around 40C though, so I can't complain!

From what I understand, the only good AM2 overclockable CPU's are the black editons with unlocked multipliers.
Everything else has to be oveclocked futzing around with the hypertransport and memory settings!
