the 295 has physX to worship or are you talking about some different ?
The CPU scores are so high because the work is not being done by the CPU, but by the GPU. The GPU is much more efficient at tasks involving physics processing. Like I said, 3DMark does not reflect real games as the GPU would be no way near as efficient at the physics processing when it also has to run a 3D app.
And yes, the 295 is PhysX capable.
The i7 system is not running the PhysX drivers as they were not released at the time or because they consider it "cheating" (which it is to a degree).
