A CPU that's pegged at 100% simply isn't wasting any CPU cycles on the idle process that runs when there's nothing else to do. An operation that pegs a slow CPU at 100% will peg *any* processor at 100%, the difference is that a faster CPU will be at 100% for less time than a slower one.
So, like I said, citing that your processor is never at 100% gives zero reference to how fast you feel your processor is, it only shows that you don't run any applications that have long sequences of instructions. It's just as possible to have a slow processor at 20% that feels like "a dog" while a fast processor that's at 80% runs great.
If you want to say "the processor is fast enough for the stuff I do", then just say it... because you look silly referencing CPU percentage as evidence that the processor is fast. It's like saying "my car is fast because it makes 20 psi of boost"... A WRX on 20psi is going to be a hell of a lot different in terms of speed than an F-250 on 20psi. PSI is not a valid measurement of speed.

So fast processors spend less time at 100% than slow processors? But I shouldn't cite how often my CPU is pegged as evidence that my CPU is fast enough?
I understand that you're trying to make a point, and that's great, but when you choose to be an ass about it, at least nail me for something I said, not something your read into what I said.
