I currently have a 2017 15inch MacBook Pro 2.9, 16, 2TB with the Radeon Pro 560. I'm running Bootcamp on it to play the occasional FPS games such as Ghost Recon Wildlands, Far Cry 5, Titanfall, Borderlands 2. Most games when I drop the resolution and detail settings run pretty well however I'm finding some issues with Ghost Recon Wildlands stuttering a lot. I'm wondering if I'll see a big difference in performance if I were to sell this machine and go for a 2018 or 2019 MBP with 32 Gigs of ram and a Vega 16 or Vega 20. I've read a few things on how the memory setup on the Vega cards actually behaves like it's double what it physically is ie: 4gb ram performs like it's 8gb's. I do not want to go for a Windows based gaming laptop due to space limitations in my apartment. This is also the same reason I've not gone iMac. Is it worth the investment? Will the Vega 16 or 20 get me through the next 2-3 years of PC gaming? I'm not running games at max resolutions and in fact run most games at 1024 x768 or 1280 x 1024 with small or medium textures. Any tips on getting better performance out of Ghost Recon Widlands? Thanks in advance for thoughts and suggestions.
