What if you have done 3D animation and no lock-ups occur? I know some
people who are doing this presently and have had NO problems.. not
even a single lockup since the latest stepping (4) of the processor
has been delivered to them.

True.. but I almost have to think that Intel would include the 10%
margin of safety on these processors, too. I have also seen some
folks with stepping 1 processors that locked up the system pretty
frequently while overlocking their 90s to 100. But, it appears with
this new stepping, some better fabbing processes were included and
they seem REAL reliable at 100MHz. How would one of these people
deduce that their processor is not working at 100. I would think it
would be pretty darn obvious (system lockups, system reboots
spontaneously, etc)..
What do you think?
