Comments (eg: how has the eGPU improved your workflow or gaming)
- I'm not sure I think it's ideal to buy a Radeon 5700 XT for gaming in macOS on a 2017 5K iMac, in particular with internal monitor acceleration.
- My tests using an RTX 2070 in Windows 10 yielded better results. But the convenience of staying in macOS is hard to beat.
- In some games, like CS:GO, the eGPU rendered a huge performance loss at 1440p, Low settings.
- I would probably suggest setting up a gaming server and streaming from it instead, to be honest.
- Moonlight streaming or Parsec gives amazing performance from my decade-old Mac Pro with a Xeon X5690 and RTX 2070. This way my iMac runs cool and the heat is generated somewhere else in my house.
- The only problem with streaming is the iMac GPU's HVEC hardware decoder being limited to max 4K. (So, no 5K streaming) 🙁
