I was in early on the 4k gaming pcs, used to upgrade the gpu every year all the way upto think a 1080-ti, then the xbox one x's come out and the 4k graphics were good enough for me to sell my gaming pc off before the parts dropped in value, have xbox series x now and even better but I used to just get more enjoyment out the pc seeing how it handled games more than playing them lol, but find once your playing alot of the extra things which impress you when you first see them tend to merge into the whole experience when your playing and dont matter as much as they do when your not playing and viewing whats on show.
series x looks great at 4k for me tho and more than good enough,
but always fun making computers and building them up and seeing that the eat up the game at full settings lol, costs alot tho haha so was glad to get a cheaper easier option in the long run
