The native OSX should be fine. It sort depends on the applications that
you intend on using. Lots of the major apps seem to have efforts to make
them work well on the altivec machines. There was a problem, something
about semaphores I believe, that caused problems with MPI apps. I ran
into it trying to get benchmark numbers for Amber and Gromacs on 4 G5
towers that I was playing with.
