3DMark06
3DMark06 combines the results from its graphics and CPU tests in order to reach an overall score. Here's how the processors did overall and in each of those tests.

As you'll see below, performance in the graphical tests in 3DMark06 are limited almost entirely by the graphics card (which is as it should be for a graphics benchmark). 3DMark06 also incorporates a couple of multithreaded CPU tests that involve physics simulations, AI, and game logic. That's where we'll see separation between the CPUs.

3DMark's CPU test give us a glimpse of the potential for quad-core CPUs in games, and indications are good. Even the slowest quad-core solution, the FX-70, comes out well ahead of the top dual-core processor.
