Ultrawide vs dual monitor oled/ips vs 4k

Hey all

Currently thinking new monitor and replacing out my IPS 34” 3440/1440. I tend to play single player adventure or indie stuff but honestly even that is lower because my main game is WoW still. I also use the same monitor for my 9-5 in IT. My gaming pc is a 7800x3d and 4070ti super.

I’ve gone back and forth a bit between 4k vs 1440p since it would be a push for my machine. I can handle uw1440 fine but burn in concerns me which is why I’m maybe thinking 2 monitors eg AW2725D for gaming and a AW2725DM for usual off screen stuff but also to act as primary work monitor.

Thoughts, recommendations? As said I have gone back and forth a lot over eg the Msi 341cqr or even the 322ur for staying on 1 monitor, saying buy once cry once and hoping I can try and work around burn in fears. My work laptop is relatively locked down so can’t hide taskbar etc.
