'The Intel Q6600 runs equally as hot as a Presler Pentium D 930, but performs MUCH better'
 
How true is the above statement?

I know Q6600 is hooter than average because it's a two dual core slapped into a single die.  
The speedcan be alots faster... If the application has support for Dual/Multicore, that it. Since most of them do nowadays I can pretty much say it Much faster than the old Intel.

How is 32c idle and 50c load when OC'ed to 3GHz sound?
 
It does run a bit hotter than a dual but not by much. It is pretty cool to tell you the truth.
 
Those are my temps and it runs cooler than my old P4 EE.

---------------

I wouldn't be that suprised if the old B3 stepping of the Q6600 ran as hot as a PentiumD 930, but the new G0 stepping has improved the efficiency a lot.

It does run a little warm but its worth the difference in performance. I run a TT V1 on mine and it's cool.

 
They are both rated at a TDP of 95w for what that is worth.
 
I suspect they will use about the same amount of power, but the D930 is not even in the same class of processor for performance.
