Hi! I've been reading these forums for quite some time, but this is my first post. I am ready to make the switch to Apple computers, for many reasons: I love OSX, I love the work of Jonathan Ives, and I absolutely love listening to Steve Jobs' keynotes. More seriously, although PCs have good hardware, I will never use Windows again. I have a limited budget so unfortunately I can't afford myself one of the new G5. But I am interested in the "old" powermac G4 since their price has lowered a little. I am comfortable with the processing power of an Athlon 1GHz, 200MHz FSB. So I would like to know if I would not loose any power with a G4 single 1.25GHz. I would throw 1.2Gb of Ram in it as I know OSX is quite memory hungry. I'll be using it for music applications (Live, Max/Msp, Peak, Protools), and a little Dreamweaver and Photoshop. Is this G4 equivalent to the Athlon 1GHz in term of raw power? I'm not so much interested in having a more powerful hardware system, I just want to switch to OSX and have a nice and comfortable system. Another question, if you're still reading me Are all the noise and heat problems of the powermac G4 a thing of the past? Or should I be expecting some annoyance here? It's very important to me as I would be using it for music so the more silent the system is, the better. I know the G4 is not the best thing that Apple has done and that it would probably be wiser to wait for RevB G5 in January hoping for a more affordable and interesting low/mid end G5 model... What should I do? The fate of a potential switcher is in your hands. I would really appreciate any help, thanks!
