Like I said in the other thread, it really doesn't matter as long as whoever you are comparing with had the same setting. I think the reasoning is that PPU offloads the physics portion (or some % of it) of processing to the GPU(s), so instead of simply testing the CPU in those tests you are using the GPU(s) as well(instead?).
I read an interesting article about this today that basically stated people had dedicated physx cards (actually you still can) before it was integrated into modern graphics cards. Therefore the whole PPU vs nonPPU test really shouldn't matter. Which for me it really doesn't, I'm not a hardcore benchmarker, I think I've run 3dMark three times ever.
