PCMark05 is a premium tool for measuring both normal home use and simple 3D performance of the latest PC hardware. There are 11 system tests - each one is designed to represent a certain type of PC usage. By running these tests, PCMark05 stresses the components in a similar manner as they are stressed in normal home usage.

PCMark05 numbers are equally impressive and overclocking boosts this benchmark score nicely.

By combining DirectX8 support with completely new graphics, 3DMark 2001 SE continues to provide a good overall system benchmark. 3DMark2001 SE was created in co-operation with the major 3D accelerator and processor manufacturers to provide a reliable set of diagnostic tools. The suite demonstrates 3D gaming performance by using real-world gaming technology to test a system's true abilities. Tests include: DirectX8 Vertex Shaders, Pixel Shaders and Point Sprites, DOT3 and Environment Mapped Bump Mapping, support for Full Scene Anti-aliasing and Texture Compression and two game tests using Ipion real-time physics. Higher 3DMark scores denote better performance.

3DMark2001 does not get much of a boost due to overclocking which is a bit disappointing to see. I was hoping for a bit more after seeing the Sandra/PCMark tests.

3DMark05's overall score does not get much of a boost either, but there is a slightly larger one in the CPU portion of the test.
