I have a pretty good RAM with 2 gb on my new PowerMac G4 Dual Proc 1.25 Ghz and the dual graphics card with Radeon 9200 and Radeon 9000. What do I need to upgrade in order to run Aperture on it? Thanks!
I read some reviews, stating the Aperture 2 is actually faster than version 1. Anyway, you can see the minimum system requirements on Apple's Aperture page.
How do you plan to transfer your images from the camera/memory card to your Mac anyway...USB 1.1 will probably not do it (and if, it will take fooorever).
Over at Apple you can find all specs for all released Macs. PowerMacs are here.
