I've seen claims that pushing frame rate to hundreds of frames/second makes a game more responsive.  For a simplistic algorithm this can be the case.  But if the input processing properly accounts for the possability for a 'button' being pressed and released during a frame, 20-30 frames/second can be suprisingly responsive.  I agree that there's no point in a frame rate faster than vertical refresh.
