Man I used to have a 980. I bet you run into all sorts of vram issues with a lot of newer games now?
That can work smoothly because 4K is exactly twice the resolution where as 1440p doesn't scale down to 1080p as well. However if you wanted to still use 1080 monitors then you wouldn't want to go bigger than 27" (well I wouldn't, you might want to check it out first) because 1080 starts to look bad from 27. Then for 4K anything under 32" you might want to use Windows scaling because text at native 4K is tiny.
If I were to make a suggestion I'd look at a good 32" 4K or 34" ultra wide (3440*1440) for immersion then if you wanted another monitor for whatever it doesn't have to match.
Solid advice.
My solitary 22 incher or whatever it is just isn't big enough to make WFH a viable experience, although I do do it on occasion (I have two in the office, and both are much MUCH bigger).
I'm not a big fan of two mismatched monitors from an aesthetics perspective though


I do look forward to sitting down and researching properly. Enjoyed it last time.
Edit: I don't play a lot of modern games as you can probably imagine! Cyberpunk and Far Cry 6 probably the newest? Currently playing the new Doom 1+2 update, Selaco (GZ Doom engine) and Age of Empires 2. While drooling over recent and upcoming games
Did this when I got my current PC too, had DA: Inquisition sitting there untouched until I bought it, and now I'll probably do the same with Veilguard!
