Re: Sanity Check: Running 4 Cards in this Configuration
How many monitors are you trying to run? You can still drive displays with the PhysX card. I have a quad display setup, with one monitor and one HDTV connected to my GTX 280s in SLI, and two monitors connected to my 9600 GT which I use for PhysX. Unless you are trying to run 5 or 6 displays. In which case I'd just say screw it and wait for ATI's six output Eyefinity 5870. But I don't see why NVIDIA drivers wouldn't be able to handle what you are suggesting, as some people are using setups like that for Folding and GPGPU stuff.
