Will my system be powerfull enough for a 4k monitor?

[Loopan]

I need your advice please

I'm running an intel i9-9900K@3.60GHz / 32GB Ram / Samsung SSD 970 EVO Plus 2TB / Seasonic Focus (1000W) PS / Gigabyte NVIDIA RTX 3080 TI with a Samsung Odyssey G7 (32") 2560x1440p monitor.

I want to upgrade my system with a RTX 4090 and perhabs with a new PS if necessary and of course with an 4k monitor (Dell G3223Q).

My problem is, that I can't buy everything at once. Besides the fact that the RTX 4090's aren't really available in my area yet.
So my short term solution would be, to first buy the monitor and wait for the rest. 

And here comes my question to you fellow pilots.

Is my system powerfull enough to run DCS at a descent rate with a descent quality in 4k?
Is there anyone out there with a similar system as mine who could answer my question?

Any opinion is very appreciated!

thanks in advance and greetings out of switzerland

Your GPU is plenty powerful enough to run 4K.

I drive 4K on a 3080 with rather high settings and I used to play in 4K with my 1080ti (with lower quality settings of course).
