We're all just hardware addicts pretending we need that 4090 Ti for "computational efficiency" when really we just want to see our RGB reflection in tempered glass while Discord runs at 600 FPS. The practical justification for upgrading is basically a rounding error compared to the primal desire for shiny new components.
