external graphics card for imac 5k late 2015

So for now carrying a laptop and a shoe-box size case for the eGPU is as mobile as I can go. Well I need to have both systems, since I require to test builds, both on iOS/Android + Win/Mac configurations. Now, you are going to reply, “ well why don’t you just buy a top windows laptop with 1060/1080 instead”. (I did try this and the airline damaged my case on the very 1st flight, and luckly it wasn’t on the motherboard side … and no refunds!) I had to switch to a laptop, because I work on the road, traveling between several different cities and therefore cannot keep checking in my desktop + monitors every time I fly to another place. I HAD a US$ 3000 desktop machine, 32Gb, latest GTX video card and all the goodies. How much was your mac setup? Just wondering word here is portability. I paid $1200 for a 32GB ROG with a 1080GTX that is getting double your fps as your external card. Its like me saying “when i use my 1080GTX, guys get this … i get more frames then my 540”.

So your telling me, your external video card that is SUBSTANTIALLY better then the junk M370X has better frame rate? You dont say.
