Got NVIDIA GeForce GTX 680MX 2 GB GDDR5 and it works. Not exactly realtime but near. (21fps from 24fps)

From the DaVinci Resolve FAQs

What is the best GPU to use for a single GPU Resolve system?
DaVinci Resolve uses CUDA technology for real time processing, and so typically an NVIDIA GPU with more CUDA cores and memory, will result in faster performance.

Resolve can also use the OpenCL technology available on NVIDIA and AMD GPUs but will default to CUDA if possible for better performance. Single GPU configurations (we call them 'Shared') use the same GPU for image processing as well as for the GUI and if you plan on using this configuration you should select the fastest GPU you can. Please refer to the latest Mac or Windows configuration guide for details.

I use an nVidia 770, they're slightly faster than the older 680's and about the same price (if not a tad cheaper).

My rig is actually a Hackintosh, but my understanding is that the latest version of Mountain Lion has built-in drivers for the 770, so as long as you don't mind not having a startup screen, it should work fine on a Mac Pro (assuming you have the necessary power connectors).

I also get a close to real time frame rate, usually starts around 22fps and picks up to a solid 24fps halfway through the clip.
