Hi i just bought my first real mac, a G3 400MHz slot load dvd imac pink with 128 MB ram. i pluged in my old seagate 80GB and installed OSX 10.4.7. needless to say the preformance is luckluster. my question is how much preformance would i get form upgradeing the CPU to a G4 550MHz 1MB L2, 1 GB ram and a DL superdrive i price up all the components at about 250 pounds plus shipping. the computer cost me 42 pounds and i had a retail boxed version of OSX that i bought when i had a hacking tosh. i have allways loved the old imac G3 and expectialy the pinks one. right now OSX runs ok with safari, msn, yahoo and itunes at the same time but i would love to do a lot more with the computer, im sure a G4 550MHz could handle iwork 06 and iphoto 06 no problems, i never liked iDVD and iMovie all that much and as for iWeb well i bought a retail copy of dreamweaver MX form a friend and its the mac version. i have to also mention that if it wasnt for the hackingtosh project i would not have switched and bought into mac software or hardware. my mum has also bought me a imac core duo 20inch pink and im awaiting its delivery im also keeping this computer pimped up in my hideaway. thanks for the help.
