For gaming in particular, the GPU is almost always the bottleneck. It's much easier to throw in more polygons and texture pixels than it is to come up with bigger and more complex gameplay simulations. I'm still running a quad-core i5 from 2014 in my gaming desktop and it rarely has an impact.
For a desktop computer even mid tier 3700X is now "good enough" even for someone with aspirations towards solid gaming.
On home use front CPUs seem to have outsprinted their usage cases.
