Still coming from PC land, I am still not caught up yet on how Apple's work. But I must say, I am starting to love everything about these sexy machines.... My question is this (now I know the g5's aren't out yet, so I'll keep this g4 orientated) - how difficult is it to switch processors in these machines? Let's just say I had a 1.0ghz dual processor g4, and wanted to upgrade to a 1.25 ghz theoritically. Is it just pop and switch? Does OS X automatically recognize it? Not that I am going to upgrade, but in the future who knows.... My concerns are more with the G5...I am just wondering how difficult it is since I have never even SEEN the inside of an Apple before. But since no one has their hands yet on a new powermac g5, I guess I am just wondering what people's experiences have been like in the past.
