Although extreme overclocking of GeForce4 Ti4400 is a very troublesome task, even a 20%-25% performance increase appears very pleasing, especially taking into account that the performance in Codecreatures and Nature tests at nominal frequencies is very low. Overclocking allows improving the situation. On the other hand, you can always use the extra performance even in weak systems or in "light" games. You can enable FSAA, anisotropic filtering, set higher resolution, etc.
