FYI:  From Microsofts Platform SDK docs on QueryPerformanceCounter

"On a multiprocessor machine, it should not matter which processor is 
called. However, you can get different results on different processors 
due to bugs in the BIOS or the HAL. To specify processor affinity for a 
thread, use the SetThreadAffinityMask function."

Not sure if this effected your results or not.
