Actually, it is a ZIF upgrade. I put Beige instead of B&W though.

The earlier PCI versions have the 40-50Mhz buses. The FSB can be a limiting factor on some things. The main thing is what you are doing. If the dataset fits into the cache than it's fast. If it's something like encoding a movie, where you need to move the data in and out fast, it will be a dog. My G4/700 upgraded 9600 sucks at video encoding but does just fine browsing the web and word processing. > The standard supported OSX on that one, 10.2 won't take too much advantage of > the dual processors, so one will be idling almost all the time....the > multiprocessor code in OSX didn't start to reach maturity until 10.4. That's what I was wondering. I've run linux for about 11 years, so I know how much better it's SMP support has been vs Windows and MacOS. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
