PhysX

I'd say it depends if you play any games that actually use PhysX. Otherwise I believe the difference is minimal if any.

It its a spare, why the hell not?

I think I'll go for it then.



Thanks guys for the assistance

I thought You needed at least 8600 to use for PysX.

Anyway depends on game, I if the game does not have PhysX then obviously there will be no diffrence. If it does then it will not noticable difference on quad CPU because CPU has enough grunt to run PhysX on CPU.

On single or dual core CPU it might help to offload PhysX processing to GPU leaving more processing power for the rest of the game, but hthen again You can offload iot to main GPU if it is not taxed a 100%.

So Only scenario where it would be worth is if both GPU and CPU are heavily loaded or if You have ATI main GPU and second Nvidia GPU fotr PhysX but it will not work on Vista because it does not allow multiple GPU drivers and Nvidia has pulled support for it in new drivers for windows 7 if Your main GPU is not Nvidia and old drivers probably will not work good on W7

Everything turned out all right. My BFG driver was able to pick up my PNY 8400GS, and I switched the physx over to it.

I read that nvidia gpu's that supported physx where 7, 8, 9 series - plus the fact that it worked anyway

The game I'm running is crysis, so yea, supports physx
