2018 15" ASUS ZenBook UX550GE (GTX1050Ti) [8th,6C,H] + GTX 1080 Ti @ 32Gbps-TB3 (ASUS XG Station Pro) + Win10 [OliverB] / Linux Ubuntu 18
-Asus ZenBook UX550GE, i7-8750H 6-core, 16GB Ram, 500GB SSD, iGPU Intel UHD 630, dGPU nVidia GeForce GTX 1050 Ti
-External FreeSync Monitor Samsung 2560x1440
-Windows 10 Build 1809 10.0..17763 (Built in OS installed by Asus)
0. Plug-in the TB3 cable.
1. Confirm everything the system tells you.
2. Done. It won`t get any easier. Plug'n'Play in every aspect.

-Performance gain 2.8x vs dGPU.
-Installation was very easy.
-There are no issues like "disabled iGPU", "black internal display", "or sleep doesn't work", "POST-issue". So it looks as those problems are Apple-made.
-iGPU, dGPU and eGPU play very well together. There is no reason for the any conflict.
-Performance is not as good as with MacBookPro (Valley Score 4527 vs 5225) It shows the superiority for performance of Macbook-TB3, directly connected to CPU.
-The UBS-C Gen 2 Port of the Asus XG Station Pro comes very handy as the Asus ZenBook does not have any LAN Ports or many USB-A Ports.
-Asus ZenBook pairs very well with Asus XG Station Pro
One of the more interesting aspects of this build is the direct comparison between a Windows Laptop like the Asus Zenbook and a MacBook Pro with Bootcamp. There two aspects, handling and performance and they couldn't be any more different.
There are quite a lot of issues you will encounter if you use an eGPU in Windows with an Apple computer. As this build is with an nVidia eGPU, we are not even talking about AMD issues, like Error 12 or the havoc dGPU and eGPU will create, if they are both from AMD. nVidia Bootcamp eGPU Issues are:
- Booting with eGPU plugged in yields a black internal screen.
- Sleeping or Hibernation will crush the system
- iGPU is switched off completely on systems with dGPU
- It's not possible to flash eGPU firmware
- Some computers won't even boot with eGPU plugged in (POST-Issue, e.g. 13" Early 2015 MacBookPro)
For the Asus Zenbook those issues are non existent. It just works, everything works, it's plug'n'play as it should be.
Some additional note about the dGPU GTX1050Ti: When Video encoding with nvenc it is clearly superior to any AMD dGPU. 278 FPS for encoding an FHD (1080p) video into HVEC (x265) is amazing.
Now, this is a different story. The 15-inch MacBookPro are famous for having their TB3-controllers directly connected to the CPU and this is clearly notable. Every benchmark or games is about 10-20% faster. The CPU of the Asus Zenbook of this built is a almost identical to the one of the compared MacBook and here are the results of one synthetic and two game benchmarks (QHD, Max-Details):

I am at this very moment trying to install the eGPU with Linux (Ubuntu 18) and doing the following steps:
1) Plugging in. Nothing happens.
2) Authorizing the device by changing the value of this file from 0 to 1:
sudo vi /sys/bus/thunderbolt/devices/0-0/0-1/authorized
The fans of the gpu are starting up and we get some result:

3) Rebooting and voilà: It boots using the external display connected to eGPU.... But there is a catch, a big one: It won't be able to start the X-Server and internal displays stays black.
4) So we need help and there is: hertg's setup script works very well, only it was necessary to set the Intel iGPU for the internal display and not the nVidia dGPU.
B) Benchmarks. Unigine Valley Extreme HD- Internal Display a good result, for external display it's not very good. Actually it is worse than the internal display and yet to be explained.
