I think it is highly unprobable that cpu gets overvolted for stability. Why for, when phenom II uses exactly the same Vcc. 6 megabyte of cache are away, why not to drop the voltage...
This is pure craziness if AMD think desktop are unimportant for power efficiency!
I highly doubt that energy efficiency of topmost priority in server systems.

If energy efficiency weren't a priority, why would they put "Outstanding performance per watt" on the front of their box instead of "Outstanding performance" or "Outstanding performance for the price?"
Also, I too heard, that AMD opteron has 80W not due to "better cores", but due to adding N while, at same time, droping total GHz ratio of CPU - to maintain TDP. And the additional cache is included in the formula as well.
This, combined with previous statement will make Opteron use on my desktop rather unefficient and unused. Well, I dont run server at home(yet), I only need boost of power maybe only some times per day.
The nice new things that I know now (and lots due to your help) are:
-) Intel is selling unlock cards for extra price for low-level intel cpus, to unlock their original performance. Pretty dirty, when a cpu that is capable at running faster with zero cost, is being added to this scheme(implementing which also ADDS extra cost) and the result is then sold at lower price. Pretty dirty.
-) Intel is selling SAS cards on server boards that are also locked! Present, working, using power, but LOCKED unless you purchase the code(600$ or so).

-) AMD sorts out bad cores for desktop, where with Intel you are running server quality(in terms of AMD) cpu on desktop system.
-) AMD uses 2 chip logic, similar to core i7-9xx. This is very probably adding to idle usage..
