PhysX card question.........

post #1 of 11
Thread Starter 
Say my mobo has 2 PCI-e slots, And say i bought a PCIe card and it will run at x16, but what if i bought a 9600gt for physx, since that is PCI-e it will make both cards run at X8, but what if i got a comprable PCI card instead of the GT, would i be able to use that as physX and still keep my main card at x16, what would the difference be.
PS. Its not a question that directly relates to my rig just a general hypothetical.

if you want someone to help you it might help if you put your actual rig specs in. seeing what you have in there now is of now help to us, and hard to look up something that dont exist.

to my understanding, once you have 2 gpu plugged in to pci-e slots it will run at 8x whether it's sli'd or CF.

you don't lose much performance, i think it's anywhere from 1% to 3%.

it also depends on the mobo. some will run x16 on main slot and x8 on the other like mine.

I always thought the physx card wouldnt affect your main card. The only way for your slot to get downgraded is if you are in sli.

I could be wrong but I'm pretty sure that's how it is.

nvm: I'm pretty sure I'm wrong lol

i don't know of any PCI card able to run Phsix.. has to be a 8600GT or better

EDIT: it also depends on the mobo, a x58 will run 16/16 where as a P55 lets say or p67 without a NF200 chip onboard will run 8/8 with a main card and phsyx card
