Is the Nvidia chipset which comes with the 12" PB outperforming the radeon9200 of the iBook a lot? Or isnt there a whole lot difference? Would it also make a difference for games like simcity4 which graphics chipset I'm using? I'm trying to decide between a PB and an iBook. It'll be my first mac.

you also have to take in account driver updates, processor speeds, ect. I'd say the 12in powerbook is a tad better. Buts that me.
