What's wrong with my CPU?

[verbatimcdr]

Hello everybody,
I got my new computer today, E6750 running on MSI P6N SLI v2, with 2 gigs of kingston DDR2-800.
my question is, when I ran a benchmark test on my CPU on PC Wizard (and also another program) I got a score which is HALF the CPU score of the reference computer which is an e6600 processor running on an intel 975 board with the same memory as my computer.
My question is, why could that be?

Possibly a multithreading error? Not taking advantage of the second CPU core? Because if its roughly half, that's most likely the problem.
