I currently have and just sold my 4800+ X2 socket 939 for $265 on an auction and bought an opty 185 for $229. I am not ready to go AM2 yet as I am waiting for the quad cores. I am thinking this is a good deal that I got paid $36 dollars to sell my 4800+ for an opty 185. Does anyone else have the opty 185 and if so what are you overclock speeds with air cooling?
