Bruce Thanks for that.
Seems Simon and I were a little crossed. He went from a 500Mhz G3 Pismo to a 550Mhz G4 Pismo. I am using a 400Mhz G3 Pismo and my mate was using a 550Mhz Pismo. So the difference I noticed was bigger than Simon (the other one) did. I have three options. 1. Keep my Pismo as it is, I mean it really is super quick anyway. I beats my sons G3 iMac 500Mhz hands down. 2. Find a cheap G3 500Mhz original Pismo daughter card and bump it by 25%. 3. Find a cheap G4 550Mhz upgrade and get not only 37% increase in processor speed but also a G4 in it to. The bonus of a G4 is that I could then run Leopard on it. And yes I know it is below Apples minimum, but I have had it running on a 400Mhz G4 Titanium PowerBook and it was ok.

For applications that make specific use of the Altivec (things like ripping iTunes and rendering movies in iMovie, the speed differences will be quite large. For straight up CPU-bound stuff, there will be almost no difference. OS X shows an improvement because it does use the Altivec in some things. Pretty much all the speed difference you saw, if it was day-to-day stuff, is the 150 MhZ difference between a 400 and 550 processor. A 37% increase in clock speed is going to be quite noticeable. If you're going from a 500Mhz G3 to the 550, it's not nearly as noticeable. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to Low End Mac's G-Books list, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
