I just recently made my own watercooler for next to nothing and have overclocked my duron 750 to 950 and I do notice a considerable difference in performance. Windows (yes windows) boots up much faster, and Operation Flashpoint is much smoother (my ti200 can finally shine a little now). Also, when you do any sort of computational programming you do really notice the speed difference. Besides the fact that it's really fun.
