I wanted to get a NVIDIA eGPU for my MacBook Pro, but it's an older model. I would plan to use bootcamp and run Windows 10 on it, since there's no support for Nvidia cards and Mac OS. My biggest question is, will it be able to be used with a TB3>TB2 adapter? Someone was telling me that there's a different amount of GB in TB3 port, than a TB2.
I was looking at the Aorus 2070 to use..
Any advice, would be great.. (besides: buy a PC, which aint happening)

You didn't say what model of MacBook Pro. Look in the builds list, search for similar model MacBook Pro and Nvidia RTX card.
Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

Oh sorry.. I didn't think that mattered.. but I have a 13" Early 2015 Retina. (I tried clicking your "builds" hyperlink and it took me to an empty page.

.The builds link is added by the forum software whenever it sees the word "builds". Links are added for other words as well. They need to update the link with the correct link:
https://egpu.io/best-external-graphics-card-builds/
The link is also found at the top of the eGPU.io web pages between News and Buyer Guide.

Thanks for pointing that out. Should be fixed now
