Using multiple GPUs for CUDA

Hi there,

I have a non-sli system, but I want to run 2 different gpus (480 and 8800) simultaneously so that I can easily switch between the two for cuda work,

I’ve got the latest 480gtx drivers installed, and have booted up, and disabled windows automatic update which instantly tries to install drivers for the 8800gts,

So at the moment the 8800gts is effectively unrecognised as a basic video controller vga compatible’, so what do I need to install, and in what order, for both the 480gtx and 8800gts to have working drivers?

Thanks in advance
