Do yu always drive at full throttle in the lowest possible gear except when braking at maximum G for a corner, as well?
Or are you just a clueless idiot?
ONLY time my CPU maxes out is doing stuff like rendering a 3D object and that takes a minute or three. If its maxed out any other time, I find out what's doing it, and kill it. Otherwise teh CPU PEAK speed is there to make things like a window round the screen happen smoothly and fast. The rest of the time CPU is not needed by and large. You want the peak speed, but you shouldn't be using more than a tiny fraction normally.
