IPS or OLED?

Hello, I just built a new pc last month, and I’m feeling like it could use a monitor upgrade.

PC specs: 7800x3d 4080 Super 32gb RAM DDR5

I currently run a 1440p 144hz IPS Acer Xb271hu, this monitor is the first generation of high refresh rate monitors if I’m not wrong and it’s now at least 7-8 years old.

I do spreadsheet, email and web surfing for work during the day. Mainly competitive games and YouTube in the evening, I do enjoy single player games with everything cranked up to ultra.

I’m leaning towards an IPS 240hz because OLED is quite pricey and I don’t really feel like babysitting it so it doesn’t get burn in (I frequently have static elements on the screen and I don’t like dark mode). I want 1440p to maximise fps and future proof my build.

My worry is that if I went for an IPS 1440p 240hz the upgrade would be minimal and not worth it, I can afford to suck it up and buy an oled.

What do you recommend for my upgrade to feel substantial?

How do older IPS 1440p monitor compare to new ones?

Thanks!
