High end nVidia cards for PhysX

A Mirror Edge based benchmark was done about 2 months ago... it showed that the original PhysX card was better than high-end video cards. That higher end video cards do much better than entry ones.

However, I personally questioned some of the numbers... I would like to see more independent tests to confirm. I would also like to see someone test the impact of number of SP, core speeds, memory size/speed, ect on PhysX.

depends on the physics calculations and the game,iirc cryostatis benchies showed significant improvement in fps for cards till 9800gtx and it trailed off after that,perhaps due to the shader performance of these cards.imo an overclocked 9800gt should be good enough.

thanks. rep+ to both. I am too cheap to buy a PhysX card anyways.

I did a test run with a single GTX 285 vs a GTX 285 and an 8600GTS for PhysX. After running Vantage a few times to verify, I actually got about 1000 less running a dedicated 8600GTS for PhysX. So I scratched the idea of using a low end 8 series card.

So do you put these cards in x1 slot and use the physx on that gpu?
