I took a plunge and bought a used AsRock Intel Arc 770 Phantom Gaming 16 GB OC, for approx. 200$ (USD). It replaced my RTX 2080TI FE.
I did some testing and it runs smoothly.
When I have VLC player running with a video on the second monitor, while playing Metro Exodus the Intel Arc 770 runs without hiccups. the 2080TI was often overtaxed while doing the same.
So all in all pretty happy about my purchase.

The newest and most demanding game I have for testing is Metro Exodus. (If Cyberpunk goes on sale I might try that). 
I use the following settings below, and on average I have a solid 180 FPS, the lowest is around 120 FPS. I use the built-in FPS counter in GOG Galaxy (not sure how accurate it is). 
One thing I did notice is that on DX12 the GPU load is lower than when I ran on DX11, the FPS were more or less the same.
