Upgrade or accessorize a MacBook Pro?
@bcarney, Radeon Pro 5600M dGPU performance is similar to the Radeon Pro Vega 56 in Blackmagic eGPU Pro. Operating noise is hard to determine. What's the typical use when the cooling fans kick on with your current 2017 15-in MacBook Pro? Have you considered opening it up to clean the cooling system and apply new thermal paste for CPU and GPU? The high power CPU + GPU in the 16-in MacBook Pro may be noisy too in clamshell mode.
