remember 20 years ago when performance really, really mattered

At this point, you could almost just assume next gen CPU is 10% faster than the one that was 10% faster last year.

GPUs are a little more wild, but that's more a side effect of all 3 having wild swings due to hardware changes and driver updates but it's still just a single graph you have to update every few months. Not really enough to run a business on.
