I apparently missed something up there. I thought this was a "I am going to", not an "I already have".
In this case, only your perception of the performance you are getting is important. You are the one who needs to be happy with it and presumably funding it. Unless you came across a stellar deal, updating the 11th gen is likely not going to be worthwhile. The i9 does perform marginally better, but also costs are in line with typical Intel pricing now that the clear out sales have long dried up.
In my own world, I have not seen any reason to spend money towards a base system update yet. My 11900K does everything I want it to and could do with a more powerful graphics card, but I just wouldn't really utilize it much with the titles I play.
IMO, Cyberpunk is a terrible title to base any systems performance on. It was poorly optimized when released, remains fundamentally flawed, especially when you consider all the resolution modifiers that came out in order for really powerful hardware to run it "well". With that said, it is a beautiful game so long as your expectations are in line with said hardware.
