Is this a good eGPU to get for my 2018 Mac Mini?

[lappy 0]

I use my 2018 Mac Mini for 4K video editing and I want to start animating some video motion graphics with unreal engine. Would this graphics card get me the power needed for what I am trying to do?

I am also ordering two 4K monitors soon and will need to have those running with this setup as well. Any pointers or info is much appreciated. If you know of a cheaper way to achieve this or a better supplier or all in one system let me know.
