We here at Big Download naturally assume you like free stuff. That's why we've got that enticing heap of files
up there, batting its eyelashes seductively at you (or maybe I need to switch to decaf that isn't laced with wormwood). But, chances are, free (
as in beer) stuff is lurking on or under your desk right this moment. No, not the cans with the five cent deposit. No, not that copy of
Daikatana you forgot to take to the pawn shop, either.
Unless you're already at the bleeding edge, got exceedingly unlucky, or are highly risk-averse, there's extra performance to be had out of the components you've already got by running them faster than their rated, factory-set speed. This practice is known as
overclocking, and has grown from a lunatic fringe cottage industry into big business, frequently with the tacit approval of component manufacturers, and occasionally engaged in by some brands themselves.
In a nutshell, overclocking allows you to get the performance of a more-expensive part -- CPU, video card, or RAM module -- out of a less-expensive one by the strategic application of brains, willpower, voltage, cooling, and luck.
