John,

I don't think you can drive 2 monitors with SLI
enabled, as the function of SLI is to use the power of
2 video cards to process one video output.  SLI is
mainly intended for computer games (and mostly the
first person shooter ones) that have a large stream of
video data that has to be processed and displayed. 
Still images in image editing programs don't put that
much of a strain on the video card.  Hopefully, you
can turn SLI on and off in software and can just turn
it on when playing games.

Mike
