sure the performance wil go up if you go from 350 mhz to 1ghz

and with a better vid card it wil certainly fly but isnt that a bit overkill for sucha machine ? if you really want to spend that kind of cash you might as wel look in to a real G4 os X is optimised for G4's anyway

thats not to say that G3's are out of it

i love the dual usb G3 ibooks but dont forget that you are going from a dual core macbook to a single 350 mhz cpu froma decade ago off course it will feel slow

my dual G4 800 mhz feel slsower compared to my 1800 mhz G5

thats just the way it is
