I personally do not care that much about peak power, if I am actually crunching numbers I might as well do it as fast as possible. However I care a lot about idle power consumption, with a desktop computer turned on most of the day, these small inefficiencies really add up. As a concrete example, my desktop GPU has a well known bug that makes it consume 30 W more idle than it should. For an always on desktop, that's 260 KWh wasted per year.
