The refresh rate hierarchy is real, and it's brutal. Nothing says "I'm technically superior" like looking down on someone's measly 120Hz monitor when you're running at 144Hz. Those extra 24 frames per second? Absolutely critical for determining whether you'll debug that code 0.02 seconds faster.
Meanwhile, your GPU is melting through your desk trying to maintain those frames, your electricity bill is approaching the GDP of a small nation, and the only thing you've actually accomplished is the ability to say "pathetic" with slightly smoother animation.
Fun fact: The human eye can barely distinguish beyond 60Hz, but don't tell that to anyone with a 240Hz monitor. They can't hear you over the sound of their superiority complex anyway.
