post #1 of 3
Thread Starter 
So I'm trying to test to see if I can get dual monitor in SLI by adding an ATi card to the 3rd slot (middle slot), but...... *sighs* might as well explain with pics.

I've tried the same thing with nvidia and ati with the same result .the drivers don't want to work together on the same system.try an nvidia card in that slot.
