So, for a while I've had 2 8800GT's in SLI on my 780i mobo, it's time for an upgrade and the 5850 is looking like just the ticket. What I'm curious about is PhysX...I feel like I read an article on here to the effect that nVidia had made it possible to have an nVidia card doing physx and an ATI card for graphics but now I can't find it....anyone know if that would work?

That question has been asked sooooooo many times now I couldn't resist taking the mickey.
