I know a guy who can get my some Socket 939 Opterons. He's an IT professional. Probably pulled from older servers, maybe new. I must admit I've fallen out of the AMD loop. The "Denmark" Opteron has twice the L2 cache that my current X2 does at 1mb per core versus 512kb. How much of a difference will that make over the X2. On overclocking. I know the Optys are good overclockers. I also remember hearing that they run cooler than the X2s. Don't know if that was just a rumor though. I don't have an overclocking motherboard. It has locked voltages. I'd like some info on which would be the best, what has good stepping, etc. I'm looking at any Opty, 170 and up.
