#3: Running the games on lower than normal settings so they'll use more CPU power than GPU power is questionable. Nobody would really do that unless they're trying to make a point whilst benchmarking. Those same games will be running at 1000 FPS in the future when we have CPUs and GPUs which far exceed todays. So yes, they can benefit from a more powerful CPU, but that point is completely and utterly stupid, just like yours is. You talk about performance per $, or you're not talking the same language as anyone else.
1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
They're about as relevant as yours.
