PCMark04 is an application-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including whole applications or using specifically created code. This allows PCMark04 to maintain a smaller installation size while still giving accurate results.

PCMark04 numbers are very close. Overclocking does not increase the overall score one bit. Like with Sandra, it does however add about 10% to the memory score though.
