well, my anecdote was supposed to demonstrate that I have a direct lived experience where hardware made a significant difference, everyone knew it made significant difference, and both that knowledge and the implications of that knowledge were part of the social game, because money and prestige was riding on it.
it is also from the world that's entirely unconnected to the American obsession with "buying the best skiis, recommended by the skiing daily magazine, before ever getting to a slope", which is a real thing, and I agree with you there.
there's definitely a Boris somewhere in the middle of nowhere who can cyka blyat on a 60mhz crt and a pentium 4 in cs:go to this day smh, and there's also a lamer with souped up ryzen who can't aim for shit. but all else being equal competitive advantage from hardware is not always and not exclusively "golden vacuum tube amp connectors".
I maintain that the people spending tons of $$$ to try and get an advantage in CS are mostly trying to buy skill, and it never works.
