Most people reading this know that an Athlon 2000+ CPU is "only" running at 1667 MHz, but they are accepting of the PR (performance rating) number of 2000 given to the CPU because in nearly every benchmark, the 2000+ CPU out benchmarks a Pentium 4 2 GHz.
For those who were not aware that a 2000+ only runs at 1667 MHz, a bit of a surprise comes when they're told by a benchmark, CPUID or diagnostic program that their CPU was not running at 2 GHz!
I'll get such a phone call or email about four times a day and when they find out that the CPU is in fact only a 1667 MHz, they're often upset, because an Intel Pentium 4 at 1.7 GHz is 33 MHz faster and costs $80 less! Never mind that in real world performance it's actually slower.
