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.

3DMark's graphics tests are, as expected, graphics bound. But its CPU tests help determine the overall 3DMark score, and those tests are nicely multithreaded. The QX6800 edges out the Athlon 64 FX-74, as does the QX6700.
