Hey there.  I think all you need to do is disable your discrete graphics chip ( the AMD ) via the device manager.

Thank you so much for this guide!

 

I have managed to get the GTX 1060 working in Windows 10 on my MBP 15" AMD R9 390x.

I will post details in my own implementation guide soon.

THANKS TO ENCOURAGING GUIDES ON THIS SITE, I HAVE MANAGED TO GET MY EGPU SETUP WORKING 

 

Macbook Pro Retina 15” Mid 2015 

AMD Radeon R9 M370X 2048 MB

2.8 GHz i7, 16GB RAM

 

Windows 10 64bit ( bootcamp )

OSX Sierra

 

Enclosure:

AKiTiO Thunder2

 

Graphics card:

EVGA NVIDIA GeForce GTX 1060 6 GB GDDR5 Memory PCI Express 3 Graphics Card

 

Power supply:

EVGA 100-W1-0500-KR - 500W 80 Plus Power Supply (100-W1-0500-KR)

 

Connections:

Molex to barrel adapter to connect PSU to GPU and enclosure

GPU powered by the PSU directly

HDMI cable to connect GPU to monitor

Thunderbolt cable to connect Thunder2 to Macbook

PSU powered on using the 'paper clip technique'

 

Monitor:

Dell U2715H 27-Inch Widescreen IPS LED Monitor

Process:

Power on and connect the GPU, check that the Nvidia is showing up in the device manager

Install Nvidia drivers

Disable discrete AMD GPU in the device manager and shut down

Boot back up into Windows10 and BOOM, Windows10 should now be using the GPU.
 

Results:

I can reliably get the eGPU to work every time and have experienced NO CRASHES!  I still play games using the AMD when I'm not at my desk, which just requires re-enabling the AMD.  Sometimes switching the AMD on and off can cause the device manager to hang, but restarting Windows 10 sorts this out so I've not had any problems using the system both ways.

 

Games Performance:

Doom - 1440p max settings - 60pfs ( WOW!!! )

Deus Ex Mankind Divided - 1440p max settings - 30-45 fps

Just Cause 3 - 1440p max settings - 30-45 fps

Star Wars Battlefront - 1440p max settings - 30-45 fps

Overwatch - 1440p max settings - 60fps

 

Getting Windows10 to select the eGPU as the primary display device:

As far as I can tell, all that is required to get the GPU to power the external display is to disable the discrete graphics chip (AMD R9 M370X) via the device manager in Windows10.  

In my experience, provided the eGPU is connected, disabling the AMD R9 will automatically cause the OS to switch to the eGPU.  Although a couple of times when I've done this without restarting, the AMD has switched itself back on!

Provided the eGPU is connected and powered on, and the AMD is disabled, booting into Windows 10 will automatically select the eGPU and you're away!
