i remember my last pc, bought three nvidia 260, hoped i could get 2 of them in sli and one as dedicated physx... end of story i only used 1 card the 5 years i had the thing, nice project.......crysis 1 was on top back then, could never get that thing playable.

the hybrid physx is no longer working with latest drivers , but 2013 games and before are all playable .
in xcom-bureau after the middle of game there are plenty of aliens and physx and need a card .
that is two month i started a new build with 3 gtx570 and a gtx280 , to play mafia2 and batman origin [that does not play with hybrid physx] with a lot of fps . batman origin is not as good as the first and the part where batman is under drugs , but some things are great , that is bad that there is no story and too much fights with too strong enemies .
the souncard is an asus hdav that has hdmi in-out , the gtx280 does the video in , hard-drives are two pci-e revodrive ;']
that should be great ....more over because i use a 2x cpu 6 cores 2.8 Ghz and 2 x 24 Go of ram .
i found nearly all on ebay at very good price . most things are second hand but all cards work and cpus + vgas are all watercooled so i think it is sure they will live long .
here is how it looks , sorry photo is not great because of not enough lights

It's simply where PhysX computations are run, either on GPU or CPU.

Auto will let it pick the best path for that game. I'd just leave it there.
