Can someone help me out? I have a dual 450 G4 tower. I am going to buy the 17" PowerBook with a single 1Ghz G4 chip. One gig of RAM will be in each. I'm using final cut, office, and photoshop. Which computer will be faster all around? The dual 450 or the single 1 ghz? As long as we are on this topic, if we are just compaing chips, does a dual 500 G4 equal a 1 ghz g4 or is the math different? Thanks for any help!!!!
