Setting up the GTX 480 with GTX 465 PhysX
Adding in a second NVIDIA card to use as a PhysX card is really easy. Eith no drivers installed we slotted both cards into the testbed and fired it up. Once in Windows we installed the latest NVIDIA drivers and after a reboot we went into the NVIDIA control panel.
From there you can select PhysX and how you want it to be handled. We have three choices; GTX 480, GTX 465 and CPU. So, what we did was select GTX 465.
I actually forgot to take pictures of the GPU-Z screens separately, but I did take a screen shot of them both running at one stage. Below you can see our two cards installed.
So, what I ended up doing is running the PhysX tests three ways. The first was just with the GTX 480 and that being also used as the PhysX card. The second was the same single GTX 480 and we selected for the CPU to do the PhysX work. Finally, we had both cards installed and selected the GTX 465 to do the PhysX work.
