Thanks xguntherc, I will have to try one of those and I was reading some your other post about this subject as well, I'm sure you helped allot of people with your knowledge.
I realised about the stepping after I posted it actually and I downloaded those two programs you suggested, it is strange though they give some big differences in core temps.
My stepping, if this is right it is C0 and on the box under S-spec it says SLAPK.
The new stepping on the E8600 is E0 which they will be introducing on all of the E8000 series I believe.
Anyway thanks heaps for your info and here is a pic of those programs, which one is more realistic do you think, +5c is a big difference.
