I am new to CUDA. I’m using a single FX4800 card on a CAD system (dual Xeon 5560, intel MB, Vista64/CentOs) I have 2 extra ~GPU slots for (1 x16 and 1 x8) and I wonder if I could add stream processors using a GTX2xx … Is this at all possible? Would Vista allow me to run two different drivers? How about Win7? I imagine I could add an FX3800 but I’d like to give it a try first using the most cost effective option.
