History: The PowerMac G4 (Quicksilver 2002) was the first Mac to break the Gigahertz barrier. Apart from the addition of a DDR SDRAM L3 cache on the middle and high-end models and several new graphics cards, the Quicksilver 2002 series was essentially a speed-bump of the Previous Quicksilver series. The Quicksilver 2002 PowerMac G4 was available in three retail configurations: The 800 MHz model, with 256 MB of RAM, a 40 GB hard drive, and a CD-RW drive, was $1599 U.S., the 933 MHz configuration, with 256 MB of RAM, a 60 GB hard drive and a DVD-R drive, was $2299 U.S., and the high-end 1.0 GHz model, with 512 MB of RAM, an 80 GB hard drive and a DVD-R drive, was $2999 U.S.
