PowerMac G4 Dual 867MHz 1.75GB Memory. My system died on me, it was seemingly long overdue. I've reformatted to 10.2.8 because it's the only install disks I still had floating around, but there's no chance I can stick with it. I've been looking around for Tiger install disks but not having a lot of luck - so I'm wondering if I should keep looking for Tiger or can my machine run Leopard smoothly? I know it's the minimum requirements for Leopard, but I've been told that if I get a decent graphics/video card for the G4 it should run well. Is this true? And if so, what card is decently cheap but suitable? Any help is much appreciated, thanks ahead of time!
