I fail to see what the problem is with citing that it's rare for me to see 100% usage of my slower CPU as support for that statement. If you've ever had a CPU pegged at 100% usage, you know what a dog of a processor feels like. It makes the computer practically unusable.
Do you see how that's different than saying "...using less than 100% CPU means your computer won't be faster with a faster processor."?
I never said (nor otherwise indicated) that it wouldn't be faster with a faster processor, nor can I undestand how you would pull that out of your ass since I know your not as simple as your acting.

Apparently it isn't as simple as you'd like to think, because CPU % has nothing to do with how fast a computer is. A given operation will have a certain number of instructions that must be executed in the processor. So it's actually how fast the CPU can execute said instructions that determines its speed. 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.
