Because the processor card in PCI Macs contains a lot more functionality than the zif in the G3's, allowing Sonnet to do it. Later revisions to the ZIF socket in G4 macs allowed the higher speeds. They were able to hack the bus/chips speed ratios to allow the faster processor to run on the PCI mac card. > Does this > limitation mean that something like a 9500 is a better cheap Mac than > a G3 > for future upgrades? Especially if you intend putting OSX on it? Hardly. For the cost of G4/800 upgrade you can probably get close to buying a G4 tower which can take faster upgrades in the future. Plus you're still hampered by the slow bus on the 9600. You can certainly buy a B&W G3 for that price, and the faster bus and AGP video on those systems makes a greater difference to overall performance than sheer processor speed. And actually, the G4 processor limit on the G3 model is higher than 400, the system I'm typing this on is running at 466 MHz. ;-) > -- "Wherever you go, there you are." - B.
