The amount of power required by a modern processor is proportional

watts here either. We tested a 3GHz Pentium 4 system and found that
its power consumption while idle was around 110W. But then we
started up SETI@home and watched the consumption increase by an
enormous 90W as the CPU, chipset and RAM subsystems swung into
saturation from the intensity of the calculations.
Get a low-energy PC. Mine runs on about 40 watts, maxing out at about
60 when working at full whack. The monitor is another 45 when on.
Fair point. There's still a non negligible energy use per calculation, though.
