Overclocking is something that can be done for whole bunch of other systems, but I never really understood the appeal behind it. True that a few games will run smoother, but the cons > pros. Unlike PC games, since console games are designed and tested with that single setup, vast majority of the games would run at speeds that are faster than what was intended by the developers. Add the incompatibility & sound warping issues, and I don't really see a point.
