I have a g3 powerbook v2 with a 233Mhz processor and 64 megs of ram....I want to upgrade this thing to make it a little faster. I was wondering if I can replace the whole motherboard with a g4 board so I can have 800Mhz on this thing, or if I can only upgrade the processor card to the 550Mhz. Can anyone help me with this little problem I am having
