I used to build (and upgrade) my own PC too, as do probably many others.
I've done no upgrades for a few years now . . and by upgrades I mean small jumps not massive performance hikes.
My GFX is still a crappy 750Ti on a B550 Gen 3 mobo with a Ryzen 5 5500 CPU and 16 Gig of DDR4.
It works, it plays some games. It won't play the games I'd like to play, even if I could afford the damn games.
Prices have left me behind, I could go second hand but don't want to go down that rabbit hole. I keep considering a PS5 for the gaming but probably couldn't handle using a controller . . and again the price of games is crippling.
I may change my name to Dude 2
