I tried the above on Windows 7 (32-bit) but could not get the second GPU to function the card is the same model I used for a Vista 64 setup (2xDVI + HDMI) I think that it was because the HDMI was not connected. I only had two monitors available but three in Vista, will try using an HDMI-DVI if I can find one. Everything looked right, Multi GPU off, Two monitors connected, correct Target and Start in paths, the second client launched but I got unstable machine errors and an EUD exceeded error in the log file.
