I was just wondering if you have an ATI Card as a Primary could you use an older Nvidia Card just to render Physx. Might be a way to have my cake and eat it too but I seriously doubt you could do that.

Been asked a few times this and the only answer is yes and no, depending on OS.

Due to not been able to use two display drivers at once in vista, it can't be done but on xp and the upcoming windows 7 it can and has been done or so I have been led to believe.

The big question is why you would want to?

Oh, and remember it is only 8 series cards with 256MB memory or more that will work.

+1 strangestranger on all counts.

Yes it is possible in Xp and Win7, no it is not in Vista.
With how 'many' good games support Physx, it does seem like a waste of cash and power...

I've done it so you can but just need an empty PCI-e port. Can't mix Radeon with nvidia though so you will have to get the PCI PhysX card which is probably obsolete by now in terms of GPU and memory clock. I don't think all 8 series or higher will work but lookup CUDA enabled nvidia cards and you can find a definitive list.

Thank You. I just want to add Physx support to my computer but I like ATI Graphics Cards.
