Hey guys... I'm in serious need of a system upgrade, as my old 700 MHz G3 iBook really isn't doing it anymore.. Anyway, I am looking at a PowerMac, but the G5's are way out of my price range for now. Basically, I can buy a stripped down bottom of the line G5, or a "top of the line" G4 (superdrive, 80 GB HD, etc.) I'm planning on buying a Dual 1.42 GHz PowerMac G4 (which is selling at a really reasonable price now.. about the same as the single 1.6 G5). Basically, I'm wondering what kind of performance differences I'll see between the iBook and the PowerMac.. I'm expecting huge changes because I've used my friends 800 MHz G4 iBook and it ran WAY faster than mine. Also wondering if you think the bottom of the line G5 would be better (even minus PCI-X, etc.) Thanks for your input.
