eGPU+'19MBPro+Rhino7 for Mac=?

Hey y’all- very new to the forum- 1st time poster.
I’m working as a set designer in the the art department of the film and tv industry. My 2019 MBPro (2.3 GHz 8-Core Intel Core i9, 16 GB 2400 MHz DDR4, Radeon Pro 560X 4 GB) has been having trouble with rendering and working in arctic mode. Very Sluggish. There are 10-15 other designers in this department and I’m the only Rhino for Mac user! Not that i’m married to it- but I want to see if I can get this computer to do what I want before I try to swap it for a PC.
I’ve headed down the road looking at eGPUs- Is Rhino 7 for Mac+MacbookPro+eGPU even a good idea? Anyone have some suggestions of products-- etc?. Any feedback is much appreciated! THank you thank you!
