My main question is whether I have the processor type set correctly? Should it be Opteron/Athlon64/Hammer/K8 rather than what I have selected as the Core 2 Duo, although it's an Intel processor, has some of the AMD-64 optimisations I believe. Or maybe I should select soemthing else completely.
A supplementary question is whether to set the "Maximum number of CPUs" to 4 rather than 2 since Hyperthreading is enabled.
AFAIK core2 duo chips don't have hyperthreading cores (you only see two cpu's right ?) or do you have the Extreme Edition (that I think may have HT enabled)
If that is the case then drop the SMT scheduler and personally for a desktop machine I would consider changing the preemption model.
You don't want the AMD/Opteron etc extensions...but if there is a Processor family that has the EMT64 extensions by default then that might be worth going for, EMT64 aside core2 is more like a Pentium mobile chip than anything else.
