There is a big difference between a Geforce2 and Geforce4 (From what I heard) You have new features like the pixels shaders, anisotropic filtering and Full Scence Antialiasing...you also have some of those on the Geforce2, but with the added performance of the Geforce4, you can't put the setting higher, therefore producing higher quality images.
