Hardware Performance - What Hardware affects "Verification on Rebuild"

So I've done a study using 4 of our most common computers and quickly learned that "Verification on Rebuild" makes a huge difference on performance (way more than I thought). That said, I'm trying to figure out what part(s) of the computer are making the biggest difference. I know it's function of CPU and not GPU, but How do I tell if it's taking advantage of multiple cores?  My test Tells me the slower Quad core beats out the dual core any day when rebuilding parts.

I'm finding that these articles are missing some important aspects of day-to-day solidworks use... that being rebuild!

I'd love to hear your thoughts / experiences!
