Nah, the Opterons are on a different core, I dunno which one... the most OCable from last I heard from the x2 series was the toldeo core models (4400/4800) But all of the are amazing processors. I'd go x2 3800 because it's a mainstream user processor. The opterons were ment only as server or workstation procs, so it's really not worth it unless you are doing lots of 3D or OC'ing a ton.
