Yes, both of you have good points. Although there is no need to compile your whole system with the optimal CFLAGS you discovered for the scientific and number-crunching libraries and programs, you might as well do it if you're running Gentoo. A big advantage I mentioned is that you can do this with your scientific libs and apps without leaving Portage behind -- at that point, you might as well compile everything else the same way.
And I assume you've already done all you can by picking appropriate algorithms and doing profiling -- using a good compiler with good flags is just the last step, not the only step.
