What are the primary differences between the "June 2004" Power Mac G5 models?
Please note that the "June 2004" Power Macintosh G5 series was introduced on June 9, 2004 and discontinued April 27, 2005. The Power Mac G5/1.8 (PCI) was added to the lineup on October 19, 2004 and discontinued June 13, 2005.
The Apple Power Macintosh G5 "June 2004" models -- the Power Macintosh G5/1.8 DP (PCI), G5/2.0 DP (PCI-X 2), and G5/2.5 DP (PCI-X) -- are the first Macs to use the 90 nm 64-bit PowerPC 970fx (G5) processor, which uses less power and generates less heat than previous chips.

On October 19, 2004, Apple added the odd ball Power Mac G5/1.8 (PCI) to the lineup, which uses a lower cost motherboard based on the one used in the iMac G5, with a 600 MHz (3:1) system bus. Apart from the slower architecture and a single processor instead of two, it is otherwise configured identically to the Power Mac G5/1.8 DP (PCI) with 256 MB of RAM (4 GB maximum), an 80 GB hard drive, an 8X "SuperDrive", 64 MB GeForce FX 5200 Ultra graphics, and 3 PCI slots. It was assigned model number M9555LL/A and sold for US$1499.
†These models have a NVIDIA GeForce FX 5200 Ultra with 64 MB of DDR SDRAM.
††All hard drives are 7200 RPM.
*Each also has an expansion slot for AirPort Extreme (802.11g) and Bluetooth 1.1.
