I have 2 LG 27GN850-B's and couldn't be happier with the choice. Here's a review of the LG 27GL850-B, which uses the exact same panel. The 27GN850-B is just the 2020 model.
Edit: Good luck on your search for a 3080. My Amazon order was canceled automatically after they couldn't deliver it on the promised date. Now i'm also on the search again. It almost seems there is no inventory at all out there. And the few cards that are there, are in the hands of scalpers selling them for 1000€+.
Yup, I've seen this one quite a lot and it seems to be amazing, I'm probably picking this one if nobody recommands me another one ^^ thanks for your answer !
