So I got this wrong again. Shame on me! Somehow I was thinking the original 2.3 was what you didn't recommend, whereas instead you say the PCIe "Late 2005" 2.3 is problematic (due to high number of faulty PSUs). Sorry again. Reliability: http://lowendmac.com/ppc/power-macintosh-g5.html Since I had a "Late 2005" 2.0 GHz Dual-Core and now have a "Original/2003" Dual-2.0 GHz, both without major problems, I'd say any statistic about faults is not applicable to a unique system like the one you may own. May be that 32% of the original 2003 2.0 GHz where faulty with their graphics cards or system boards, but mine is fine anyway. (Until now at least.) To come back to Bob's decision finding: For both 1) the more efficient PowerPC 970fx and 2) PCI-X with eight DDR2 DIMM slots, these two models remain: PowerMac7,3 Mid-2004 Dual-2.0 GHz PowerMac7,3 Early-2005 Dual-2.3 GHz All others are either not using the 970fx or don't feature PCI-X, and with PCI they only have 4 DIMM slots. All Power Macs with PCI/PCI-X can take 1 GB DDR-DIMMs, so the PCI-X models max out at 8 GB (the PCI models at 4 GB). The all take PC3200 DDR RAM at 400 MHz. Bob said, he wanted to reuse some of his RAM that he had for his G4 MDD Dual-1 GHz. The MDD Dual-1.0 GHz and Dual-1.25 GHz as well as the FW800 Dual-1.25 GHz and Dual-1.42 GHz uses PC2700 DDR memory at 333 MHz The MDD Dual-867 MHz and the FW800 1 GHz use even slower PC2100 DDR memory at 266 MHz. In short: MDD/FW800 with 133 MHz system bus: PC2100 DDR (266 MHz) MDD/FW800 with 167 MHz system bus: PC2700 DDR (333 MHz) G5, all but "Late 2005": PC3200 DDR (400 MHz) While you can (propably) use a faster memory module in a slower memory slot (i.e. a PC3200 in a G4), you cannot use a PC2100/PC2700 for a G4 in a G5. Keep that in mind.
