It's not really like overclocking. Overclocking is taking components past their design limits to improve performance.
All changing DPI does (for a given mouse sensitivity setting in an OS or game) is change how far the mouse cursor moves given one inch of mouse movement.
For example, I have my in-game mouse sensitivity for MW2 set quite low, so that it's comfortable to move around at 3000 DPI. I retain enough accuracy to attack targets, but can quickly snap 180s or make large aiming adjustments. By bumping down to 2000 DPI, the same mouse movements move my in-game cursor much less, meaning I can't as snappily react to nearby targets, but have steadier aim for sniping. Conversely, bumping it up to 4000 DPI means that very small gestures cause big changes in direction, which is bad for aim, but great for less precise weapons (like shotguns) where close enough and firing first matters more than a perfect shot.
