These forums were extremely helpful in getting me up and running with my 2014 15" Macbook Pro GT750M + GTX970 + Win 8.1 + AKiTiO Thunder2. I've been playing Witcher 3 at 1440p on Ultra with this setup and its been great. The only issue I ran into is that I'd hoped to continue using my Henge Docks vertical dock with this setup but I can't. One thing I tried was docking the Macbook, having one TB port go to the monitor as HDMI with the GT750M, another go to the eGPU -> monitor w/ DVI and then rebooting. But when Windows boots up, the GTX970 doesn't show up under Device Manager. Any thoughts on how I can get this to work or should I just give up?
