I'm making the jump from the 560x from my 2018 model and wanting to grab a used MBP 15 with the Vega, but unsure which one to grab (I do photo work and some video rendering, and light gaming via Bootcamp). I've read some benchmarks that put the Vega 20 30% over the 16 and some reviews suggesting the i9 isn't money well-spent because of thermals. Any helps would be appreciated! Thanks
