All things being equal, the Opteron will be the better overclocker. This is due to the fact that they use higher quality silicon wafer and the Opterons are designed for 24 hour uptime server / workstation use. Quality control and everything else is pretty much better all around. So if you have a Athlon 64 X2 and Opteron with identcal specs, I'd bet on the Opteron being more stable at high clocks.
