Are you using BootCamp or Parallels VM for Windows 8?
While I am aware of the lack of performance with Parallels, my luck with compatibility does improve. Parallels Tools works wonders with my computer, but it isn't dual GPU, so its worth a try. Get the trial version of Parallels 9 and see if it works
I've done some research, but it applies to PCs directly- it could be different on a Mac Pro.
"You can have one card keeping Max responsive, and the other doing the VrayRT render.
Or you can have both cards doing the VrayRT render but you may notice significant UI slugginess if the settings are taxing the cards.
I'm not sure if Max can utilize more than one video card for itself."
I suggest using a tool such as atMonitor to visualize your Mac's performance
From there you will know if 3ds Max can utilize the 2nd GPU
