Ideally I would like a 1GHz G4 upgrade for my B&W G3, but I can't really afford that. So, the next best thing, a 500MHz G4...these go a lot cheaper than the 1GHz for obvious reasons. But is it still worth it?

The benchmark results on this page seem to suggest it is worth it, and this is based on a G3/400, not a 300MHz like mine.
