If you look at the game recommendations it says a gtx 285 or higher and I have run mafia 2 with my gtx 260 core 216 used as a physX card and another gtx 460 as my main and experience no problems. So ya a gtx 460 would work great however if your looking to spend less you could always try a gtx 285 or something in that range.
something to keep in mind to now this is just my opinion but as of right now personally i feel physX doesn't really improve the gameplay in this game or many others for that matter just adds and extra level of depth to the pedestrians and ppl flying around
If im reading your post right you intend to use ATI for main rendering and a nvidia card for dedicated PhysiX.
If this is indeed the case then without using hacked drivers or some such you have no chance. As i understand it the Nvidia drivers will do this.
"Nvidia's graphics drivers deliberately disable support for on-GPU PhysX physics processing when they detect an ATI graphics card present in the system - something that has apparently been happening since version 186 of the driver"
You can Google this quite easily and see what the issues are and what the possibilities are.
Can't find your answer ? Ask !

I know i need to hack drivers, but i think Nvidia is beeing stupid at that point.
1. I am buying Nvidia card = I am not steeling Nvidias technology and simply want to use NVIDIAS card to use their own technology.
2. From what i have seen Level of detail is amaizing.
I found old 8800GTS and i have a problem.
When i plug it in 2'nd slot with my ATI at the 1'st (TOP) slot, windows gives me blue screen upon sturtup.
Do i need to reinstall windows or can i fix this somehow ?
