Does the GPU actually make much of a difference to SketchUp itself? I've heard conflicting comments, and I guess with the eGPU it's easy to see the difference as you can just unplug it.

I just tested 2 scenario's using the CrowdTest 3dModel from the 3dWarehouse.

First: Laptop with eGpu connected (gtx1080) with two large monitors. Biggest Scene(11) runs fine - eGPU 40% used (Task Manager)

Disconnecting the eGpu while running SketchUp crashes SketchUp (and Unreal etc). Makes sense though.

Second: Laptop running on its own (integrated gpu), only laptop display. Already in smaller scenes SketchUp is showing simplified geometry instead of the people. Big delays while switching between people and the simplified geometry.

So for me, and the dual external monitor setup, already in SketchUp it's a big difference. I can just focus on my work and don't get annoyed that much by SketchUp's performance (unless I run a plugin while the Outliner is open, or LayOut is freezing for half a minute while updating etc.)

It will depend though on your models. I rarely exceed 500k edges.
