There's one more aspect to it. If you lower the CPU clocks/second artificially, some games start frameskipping internally when they can't keep up, which can "improve" gameplay performance (although wrecking the framerate) on very weak machines.
This can cause strange issues in some games though so it's best viewed as an ugly performance hack.
