My PowerPC Mac's don't seem as fast as they should. It's my understanding that now that Macs are made with Intel processors they're much faster now, but were they actually as slow back then as they are now? I don't have a G5 Mac so I can't say for that, but it seems that my 500MHz Compaq Deskpro performs the same on Gmail as my Dual Processor 1.25GHz PowerMac G4...Idk, it could be just me. Mine are generally slow now, but were they fast back in their time???
