I will do and I'm expecting huge results. The thing is I really don't want to use W10, I'd much rather figure out why OSX isn't playing nicely. I suspect it's the TB2 connection - remind me your setup?
I’m not sure. I think it’s the Nvidia drivers to be honest, super under perform. I only use mine to game in Windows - 2017 13 and a 1070, and it performs great.
You may be better off with an AMD card for macOS, I keep meaning to test out my 580 from my Hack.
Yeah thats a very good option... a quick google tells me no GPU can power any thunderbolt screen as mini display > tb1/2 adapters dont work.
Have you tried any benchmarking in W10 yet? Because I bet you'll see massive improvements compared to your macOS scores.
