Perhaps ... but what the site arguably does well is tout software.
Trying those tweaks initially upon my first exposure to Vista made little,
if any, difference in its performance ... resulting in undoing most of the
"tweaks".
Based on that experience I would have to say that the benefits of the
"tweaks" are more than likely system dependent, not necessarily gospel, and
YMMV.
