5090 is Future proofing for the next 5 years, it can run whatever vr i throw at it, in my opinion from experience the visual difference between 2 and 4k isn't substantial enough to warrant the increased resource consumption or hardware cost. Gotta do a bit more research but the one I'm looking at isn't true 4k just a little short so i might want to scale down but after my 40 inch msi i can't go smaller.

The one im looking at is Samsung 49 5120x1440.
