With 3DMark2001SE you can see a huge improvement in performance when going from 133 FSB to 166 FSB. From 166 to 200 there is 437 point increase then another 58 points gained when going to 215FSB. The score difference between 133 and 166 FSB is really impressive. After getting to 200 and 215 FSB the overall score is really good even at 640×480.
There is the same kind of large increase in performance with Jedi Knight II when going from 133 FSB to 166 FSB. Above 166FSB there is really no difference in frame rate, and would not be noticeable at all. You can truly see the difference while overclocking though.
With Quake 3 the increase is much less impressive when compared to 3DMark2001SE and Jedi Knight II. You can see the larger increase in frames per second when going from 133 to 166 FSB however it is not as good. After 166FSB the increase is not very large like the testing with Jedi Knight II.
Unreal Tournament 2003 does a flyby and botmatch test when the benchmark runs. Once again the improvement between 133 and 166 FSB is large like with the other testing. Once above 166 FSB the increase in frame rate is very low and would be unnoticeable if actually playing the game.
