Multiple GPU's Running Multiple Monitors?

I've got a working hackintosh build with the following hardware: GigaByte ga-b75m-d3h Intel i5 3330 Geforce 8800GT

I have just received a Geforce GT 710 and I am hoping to get it working to run a third monitor. This setup works fine in windows with all three displays.

When I boot into mac os it appears to initialize a display from the second card but goes into a loop. https://imgur.com/a/wey87

Any thoughts or ideas would be greatly appreciated.
