Will installing the Dec2002gccUpdater.pkg (gcc 3.3) allow me to generate G5 optimized code using Jaguar and a G4 machine?

Yes.

How important is this?

That depends on your application. Just using the compiler's built-in G5 optimizations probably won't do all that much for most applications. Doing dedicated G5 optimization on performance-critical routines, though, could result in significant performance boosts depending on how many independent instructions you can keep in-flight at once.

You'll definitely want to install the CHUD tools so you can use the Shark profiler. This will point out the performance hot-spots in your code. You'll want to run your application under CHUD on both a G4 and a G5, because the performance characteristics of the processors are different. Nonetheless, it would not be unreasonable to guess that some G4 performance hot-spots could also benefit from G5 optimization as well.
