I am going to be buying a legacy mac...possibly a PowerMac 9600 or G3 Tower. Would gentoo run smoother on a G3 1Ghz or like a G4 500Mhz?

I have no test results to back this up, but I would guess that out of those two the 1 GHz G3 would be a lot faster. It would get a lot more interesting if you were running a heavily Altivec-optimised program, or if the G4 had 2 CPUs.

Unfortunately, GCC isn't yet very good at producing Altivec code, so the vector code usually has to be written by hand in assembly - hence most Linux apps don't use it. SMP, on the other hand, gives very noticeable performance improvements, especially in heavily threaded programs.
