I don't know if my Athlon experience will help you any but I went from 31 FPS with an Athlon 1800+ and PC2700 ram to 44 FPS with an Athlon 2800+ using the same ram. When I upgraded to PC3200 ram I saw about a 2 FPS increase. I think you may see a higher increase going from PC2100 to PC3200. As important as the bus speed rating of the ram is the wait state rating is equally important. You want a rating of 2CL over the 2.5CL or 3CL rating of cheaper memory.
