I'd say I'm somewhere in the middle too. I also have this tendency to build high mid-tier as my budget allows then ride it for 7 years or so until the games I play start struggling. I just don't have the money to keep up with the latest and greatest/upgrading every year.

...admittedly since Baldur's Gate 3 came out I've been using my PC as a space heater so take that as you will...
