What would be a worthy upgrade from a 32" 4k ROG Swift PG348Q's gaming monitor to

Yo people of reddit!

As I had just upgraded my system to a 5090 build, I'm now looking to also upgrade my panel. First I was looking at the big boys monitors like 49" Samsung Odyssey OLED G9 S49CG954SUSamsung Odyssey OLED G9 S49CG954SU, but after investigating, that they aren't really good for gaming. And that most information I gathered is that the best gaming experiance people were getting, is still the 32" 4k 21:9 monitors (Not sure how much comes down to personal pref.).

Things that the monitor primable is going to be used for.

- Single player games. That's it :)

Almost no limit on budget, but I dont see the point in buying spec that I dont have a need for.

My own research has kinda landed on this monitor

34" Dell Alienware AW3423DW - 3440x1440 (WQHD) - 175Hz - Quantum Dot OLED (QD-OLED) - USB 3.2 HUB - Curved4" Dell Alienware AW3423DW - 3440x1440 (WQHD) - 175Hz - Quantum Dot OLED (QD-OLED) - USB 3.2 HUB - Curved

But is that a worty upgrade from my previous monitor? I know my old monitor, is an older monitor, but was super exspensive when I got it, and it was top of the line at the time. - So is the a worthy upgrade? Or would you suggest something els? Maybe 240hz monitor? Or is that even something I would notic when just playing SP games?

/Cheers for your input!
