Installation steps 

MacOSX:
Didn't bother as there are no drivers for the RTX Series (Turing Chip).

Windows (Recommended Windows 10 Build 1803)
1) Boot without eGPU Plugged in (It's actually not possible to boot with it the eGPU being plugged)
2) Press ALT for the Bootloader
3) Select Windows and wait for the dots appear cycling "plug-ready"
4 When the dots reach first the upper part of the cycle, plug in the eGPU (This is the only difficult thing here, this is a matter of timing).
5) After Windows is loaded, check for "Display Adapter"s under "Device Manager", if there is a Microsoft Basic Device Adapter (Error 31).
6) If it is not there or something else went wrong (BlueScreen, Didn't Boot at all, etc..) Repeat from 1)
7) Install latest nVidia Driver
8) Hot plug n play the eGPU as you wish. You may even connect and disconnect the eGPU via button in the down left corner of windows.

It works very well, but when you reboot/start the system you have always to hotplug the eGPU at the beginning (Step 4). Once the system is running, you can hotplug and hot-unplug again and again. This solution is best, if you work mostly with Windows. You can let it running.

Comments 

1) About the gpu hardware:
The production quality of the Asus RTX 2080 Ti Dual is amazing. It's big, heavy and feels great with a thick metal plate at the backside. Furthermore the fans are absolutely amazing quiet. You don't hear them at all, even at high loads, they stay under 40dbA.

2) About the extra USB-C Port of the RTX 2080 Ti:
It works well as output for the 1440p Monitor. It should work, too, for any 4K-Display but not for 5K-Display. It can generally be used as a port for any USB-C hardware, but not on this setup. This has the same reason, no eGPU Ports work at all with Bootcamp and 13-inch MBP 2015. It works well with a 15-inch MBP 2018 though.

3) About Performance:
The working performance (OpenCL, CUDA) of the RTX 2080Ti is just great and worth every cent, the gaming performance is somewhat disappointing. The examples in this post reflect the overall performance improvement from  the RTX 2080 Ti to the GTX 1080 Ti:
-about 80% in working/calculating
-about 15% in gaming

Reasons for these could be:
a) The Geforce 1080 Ti is a highly optimized gaming machine
b) The Thunderbolt interface slows down the RTX 2080Ti. It's the first time it's notable.

Note: - It is not advisable to run a 2,7slots card with the Asus XG Station Pro closed. It fits, but because temperature increases and performance drops.

Can you upload 3Dmark like firestrike or timespy? It seems half TB3 bandwidth made the performance also down to around 2080 performance on Forza Horizon 4.

Soon I will add my system & eGPU details or a build link to this my signature to give context to my posts

@oliverb, thank you for posting about your experience with the RTX 2080 ti on the Asus XG Station Pro. I have seen that the RTX 2080 ti can have peak power draw just under 330 watts. For the most part, it seems to run sustained around the 270-280 watts. Given the 300 watt limit for this eGPU enclosure, have you notice any issues with there not being enough power? I am referring to solely running the GPU and not trying to charge through TB3 as well.

In my setup there are no issues because of the power. The MPB need an extra power cable anyway.
