Overclocking and PhysX
Just checking to see if anyone else has done something like this to maybe save me some time.
I currently have a GTX280 as my main GPU and an 8800 GTX as my PhysX GPU. I know it's not really necessary but I was looking into overclocking the 8800GTX for the best PhysX performance and I was wondering where I should focus my efforts. Core, shader, memory? Is one of those things going to be more important to the PhysX performance than the other? I'm guessing the shader clock but I don't know how much the core frequency or memory bandwidth play a part in the overall PhysX performance. Ideally I'd like to only overclock the parts of the card that are going to make a decent difference to keep temps down and prolong the life of the card. (I know, if I wanted to do that I wouldn't be overclocking it at all).
I'm planning on testing my changes with FluidMark. Does anyone have a better suggestion as to a benchmark to use? Any recommended settings I should consider?
