Edit : CPU-Z isn't working properly yet with windows 8 here.

Well, I know now why CPU-Z is borked and will remain so. Windows 8 uses the APIC timer - to get the CPU frequency for the TaskMan, I guess, the timer which is the same unshareable system resource CPU-Z, AIDA 64 and other tools used to use to get the CPU operating frequency. Win 8 also resets it on-the-fly.

They (CPUID, Aida, etc.) are now all left hanging in the wind.
