Help with ultrawide monitor upgrade

Hi all, hope everyone is staying safe and taking the time to fly more!

I have a 34 inches ultrawide IPS Panel with full HD (2560 x 1080) lg-34UM58 and I have been looking for a change to a curved monitor to get a more immersive experience and also read that even for work it is good in terms of fatigue.

I work with IT so can really use a big workspace as I usually have a least 2 active windows at any given time. From gaming point of view I currently only play MSFS 2020 but may occasionally play some FPS or racing game. I am currently running on these settings at 1080p and would like to keep them if possible with the new monitor (even if that means scaling down the resolution a bit - see below):

Enable TAA
Terrain Level Of Detail - 100
Terrain Vector Data - High
Buildings - Medium
Trees - Medium / High
Grass And Bushes: Medium
Object Level Of Detail: 100
Volumetric Clouds: High
Texture Resolution: Medium
Anisotropic Filtering 16x
Texture Supersampling: 4x4
Texture Synthesis: High
Water Waves: High
Shadow Maps, Terrain Shadows: Medium / High
Contact Shadows: High
Windshield Effects: High
Ambient Occlusion: Ultra
Reflections: High
Light Shafts: High
Bloom, Depth Of Field, Lens Flare: High

My PC specs are:

  • i7-9700KF 8 cores @4.9
  • Geforce RTX 2080
  • 32 GB (4x Corsair Vengeance Pro RGB 3000MHz)
  • OS HDD: Crucial P2 500GB
  • DATA (where I put the games): WDP Blue SN550 1TB

I am not looking into upgrading in the next 1 or 2 years (maybe in 2 years I will replace the whole thing but I wanted to keep the monitor I am buying now for 4 years or so), but I do believe I can still push my hardware a bit harder with a new monitor to get better experience, say with HDR and QHD.

I have been doing a lot of research, but again getting a targeted opinion to my case it would be ideal, so far what I am thinking:

  1. My current setup is definitely not enough for 4k gaming in general, however the question I have is: is it worth buying a Dual QHD or 4k monitor now and changing the scaling say to 70/80 percent?
    Given the above is a possibility I am looking into one of the following:
  2. Buying a 1440p ultrawide - 43 or 49 inches (21:9 or 32:9/10) - in this case I something like a AG493UCX - 5120x1440 @120Hz with PBP support for AUD 1400 or a CRG90 as it is currently on sale at Samsung for AUD 1600
  3. Is 1200 vertical too bad of an idea? have liked the XG43VQ - 3840 x 1200 at 120 Hz PBP support for AUD 1200
  4. It is not worth upgrading to a 38 inches ultrawide (1440p or 2160p) - not very sure on that one but opinions are more than welcome

One feature that I really would like is built in KVM so I can switch between my gaming desktop and work laptop, but again it can easily buy a USB switch for my infrared keyboard/mouse and use an HDMI for work and DP for gaming.

Update - just adding the pixel count here to make it easier:
Today: 34" 2560x1080 21:9 = 2,764,800
Standard QHD 16:9 = 3,686,400
Standard 4k 16:9 = 8,294,400
Ultrawide 43" 3840x1200 32:10 = 4,608,000
Ultrawide 49" 5120x1440 32:9 = 7,372,800

Any feedback is appreciated, thanks in advance community!

Here’s how I abuse the heck out of my stuff, some involves editing the user config

I’m on 5760x1080 on 9900k Oc;ed 5ghz 3060 12gb Oc’ed too and 64 gb of ram with loads of drives holding bits of things quickly.

Oh and there will be antialiassing issues at ultra wide but they are getting better.

Thanks @Salem978 ! Considering the RTX 2080 can handle a bit more (from what I know) I think it would be possible to do 5760x1440p at Medium / High settings to get at least a solid 30fps?

ooh thats actually more than 4k i think 5760x1440=8,294,400

im pushing 6,220,800 with a 3060 12gb and really feeling it.

edit:though you 2080 is actually faster

Makes sense, would you say that just by having a bigger screen, curved, HDR (don’t have now) and better refresh rate (from 60Hz to 100/120/144Hz) will already give me a lot of improvement compared to what I have now - say even if I go for 5760x1440(or 1200) and reduce scaling to 80% or something?
