I am building an eGPU setup with my Macbook Pro, looking to boost the performance. What graphics card should I buy?
RX Vega 64 (GIGABYTE)
GTX 1080 TI

A Vega 64 will get you the smoothest macOS compatibility. 1080 Ti can get you more performance in some cases, but it requires some hacking to make work (and doesn't work at all on macOS Mojave at the moment due to lack of drivers).

Good day to take it out, MacBook 15 Retina 2013-2014 with graphics only Intel will work with Razer Core, Razer Core X and NVIDIA GTX 1080 in Windows 10?

Ah yes?! Isn't this depending on the OS?
The precise answer is:
Vega 64 for MacOSX,
GTX1080Ti for Windows

Elaboration:
- Vega64 is better in MacOSX than a GTX 1080 Ti and works in Mojave, which the GTX1080Ti doesn't.
- GTX 1080 Ti is much better in Windows than a Vega64, it's over 30% performance gain.

If you have a look at this Radeon VII vs GTX1080Ti comparision  you can see that the GTX1080Ti is clearly better than a Radeon VII, which itself should be better as a Vega64 (it looks as this is not always true).

#FACTS!

Absolutely a great point! That is 100% Correct. The Vega works in Mac OS vs. the GTX and the GTX works in Windows vs. the Vega. Now the question I want to know is, does the Vega work better in Windows over how it performs in Mac OS?

if you used performancefactor mV,wV and mG,wG in order to describe the relative performance of the cards it will rise the question: What is the exact equation to determine the balance?
It is:
(mV+wV)/(mG+wG)
or rather
mV/(mG+wG) + vW/(mG+wG)
or
1/((mG+wG)/(mV+wV))?
or
e^(log(mV+wV)-log(mG+wG))

You lost me after you added the alphabet to math.

One thing to add:

When it comes to AMD vs NVIDIA, you should question yourself if native eGPU OSX support is a must or not

I would prefer to buy an RX 570 4GB or 8GB at the moment.
What do you mean by "native eGPU OSX support"?

@aurumnus native support means no additional software or hacks needed. RX 560 to Vega 64 GPUs all have built in support in the latest macOS built in drivers. In practice this means you need do nothing more than plug in the eGPU and it works - as an RX 570 will on a TB3 equipped Mac running 10.14+

2017 13" MacBook Pro Touch Bar
GTX1060 + AKiTiO Thunder3 + Win10
GTX1070 + Sonnet Breakaway Box + Win10
GTX1070 + Razer Core V1 + Win10
Vega 56 + Razer Core V1 + macOS + Win10
Vega 56 + Mantiz Venus + macOS + W10

It should just work, it would be yet another GPU in the system. The problem might come with which one a game will use by default. You can switch this in the nvidia control panel, or worst case disable the 1050 altogether in the device manager if you run into issues but if I recall the HDMI port in those X1 is connected directly to the dGPU so not sure that's the best method. It will work, but just not as clear cut as with a laptop that doesn't have a dGPU, but it's not super difficult. Probably the nvidia control panel route is the way to go.
