Howdy 
An utterly n00b question, but I've had nvidia cards for yonks, and recently grabbed a 4870.
I'm very pleased with the performance of the card so far, but I was wondering what happens in regards to physx when it comes to ATI cards.. will it all be done on the CPU? Is it possible at all to use my old 9600GT as a dedicated PPU? I assume not, as it'd mean having both nvidia and ati drivers, but it's worth a shot
Running Vista HP64, if it makes any difference, and cat 8.11's.
Cheers!
