Why buy DDR2-1066 when so many DDR2-800 modules are perfectly capable of reaching these speeds? Equally remarkable is that the Ballistix and HyperX UL modules both achieved this speed at tight 4-4-4-8 timings, but will this put OCZ behind in benchmark performance.

There is no noticeable Direct3D performance difference between the three module sets at the lowest stable DDR2-1066 timings, and only Maya showed any realistic difference in OpenGL with the Kingston HyperX UL modules falling slightly behind. The Maya results were probably just an anomaly, since they didn't pop up in any other tests.
