Is eGPU an option for this monitor setup for 2015 15" mBP?

First time poster here...

I have a mid-2015 15" MacBook Pro dedicated graphics.

  • macOS 10.15.1 (Catalina)
  • i7 2.5 CPU
  • 16GB RAM
  • 512GB SSD
  • AMD Radeon R9 M370X

Am planning to go for multiple monitor setup (3 o 4 plus the internal display). Since am using a 5 year old machine, resources who had the same monitor setup are rare to none. Monitor setup I had in mind are:

  • 2 x 2k/1440p monitor (via active thunderbolt 2 to DP or HDMI)
  • 2 x 1080p monitor (via HMDI to HDMI and USB3.0 to HDMI)
  • mBP internal display on (2880 x 1800)

Well am uncertain that setup can run without an eGPU, so I need a plan B which via eGPU.

Are there any recommended build I can follow? Or are the builds compatible to current macOS versions?

Pending: Add my system information and expected eGPU configuration to my signature to give context to my posts

@nanojava, You'd need an eGPU to run four external monitors. I'd recommend a Sonnet Breakaway Box 350 + RX 580 and Apple Thunderbolt 3 to Thunderbolt adapter. You'd need Purge-Wrangler scrip to enable eGPU feature in macOS for your Thunderbolt 2 2015 MacBook Pro.

@nanojava, 3 external displays are doable. A fourth display from USB 3.0 can work but it would use DisplayLink which is not perfect in macOS but might be good enough for you (you mention USB3.0 so does that mean you have experience with DisplayLink?)
