This is due to the lack of AltiVec in the G3 line of processors and the fact that most pre G4 and early G4 systems do not have video hardware capable of supporting Core Image, two technologies Leopard relies heavily upon among others. Leopard can be "hacked" (see below) to install on these G3 and pre 867mhz G4 machines but the system may behave erratically and many of the programs, features and functions may not work properly or at all." - Wikipedia

Well it seems that it is possible after all with a little hacking done, but i don't think it's worth the effort ( stability and performance....ugh ) Tiger is good enough
