Dont know if you already figured it out but just to be safe, the answer is yes. The GTX 670 is supported in Resolve. Im using one in my machine and I get real time playback, no hiccups, no fuss no muss.
On Windows 7 with Resolve Lite if I have the Quadro 600 and GTX 690 cards installed, I will get 1 GUI and 1 GPU right? But if I upgrade to the full Resolve I will get 1 GUI and 2 GPU right?
Does this mean I can now run a "dual" GPU on my Asus P9X79 Pro motherboard if I used both a Quadro 600 and GTX 690 as long as I upgrade to the full version of Resolve?
