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.

2x 512MB Mushkin HP3200 Redline (261/522)	28416

Looks like simply boosting the memory operating speed is not enough for 3DMark2001 to notice a big difference.

3DMark05 is the latest version of the highly favoured 3DMark graphics benchmarking series. It is the first benchmark to require DirectX®9.0 compliant hardware with support for Pixel Shader 2.0 or higher.

3DMark05's overall score is more videocard related, but the CPU section gets a decent boost due to overclocking the Mushkin HP3200 Redline modules.

X2: The Threat	Source: Egosoft

A completely rewritten 3D engine based on DirectX8 encompasses many visual effects such as volumetric Nebulae (gas clouds) that have a real impact in the game (you can hide in them) and many new engine, shield, weapon and explosion effects. Objects cast real dynamic 3D shadows! Dynamic DP3 bump mapping allows a previously unseen level of detail.

Rather disappointing results here; it seems like raising the memory frequency does not boost performance very much at all. Considering the Athlon64 memory controller on all setups is running at the same speed, I guess this is not surprising.
