You also have to consider power consumed. Modern cpu's use less electricity, but give better performance. This is particularly important in systems that run at 100% for hours/days eg I do a lot of 3D rendering.
You could argue that hardware upgrades benefit the environment.
...but not our finances, and not everyone does that kind of work. But MS has convinced everyone they need a buggy new OS every few years. By the time the bugs are worked out, they develop a new OS to replace it. It's a racket. The $200-250 I would spend on a new machine would far exceed any savings in electricity. Although it might not be true for you, MS paints everyone with the same brush.
