Faster cpus become more power-efficient cpus because they can race to sleep. So you really do want to pay more for that cpu, but not for the compute performance but for the battery life.

That's assuming the faster CPUs use the same amount of power. It's possible for a slower CPU to have better performance per watt. This is often exactly what happens when you limit clock speed -- performance goes down, performance per watt goes up.
