I see that my previous posts have been deleted so I obviously crossed a line and I apologize for that.

the Nvidia units have that already built in so no need to offload that on the CPU hence better physics scores as no delays in speed that the CPU can do it compared to a dedicated Processor that is made especially for the job!
and if u do not believe me fine go look that up for yourself and go to the nvidia page and u can learn a lot about that part
First of all you have to understand what you read and you don't no matter what they say at the MSI forums.
Do you understand what this means?
"PhysX is a proprietary realtime physics engine middleware SDK."
"Video games(or benchmarks) supporting hardware acceleration by PhysX can be accelerated by either a PhysX PPU or a CUDA-enabled GeForce GPU (if it has at least 256MB of dedicated VRAM), thus offloading physics calculations from the CPU, allowing it to perform other tasks instead. In theory this should result in a smoother gaming experience and allow additional visual effects."
You need to read this to:http://en.wikipedia.org/wiki/Physics_engine
Now go and check which physics engine Futuremark has used on 3DMark11 then you can ask Futuremark if they allow physics to run on either Cuda cores or a PhysX PPD.
And please post back with your findings
I've got more than 100 results with different GPU's to show with both NV GPU's from GTX480, GTX580 and GTX680 and AMD GPU's from HD5970, HD6970 and 7970 and I KNOW that PhysX has no effect on the physics score. In earlier 3DMarks like Vantage 06 it does but your score will not be valid.
