    Specs:
    G4 1.5Ghz, 2GB RAM, DVDRW, 360GB HDD
    CPU Upgrade for G4 "Sawtooth"
    I recently upgraded my G4 350 to a PowerLogix 1.5Ghz CPU. It made a MASSIVE difference. But I was wondering, with the standard G4 logic board, should I have just gone to a 1ghz or similar? Basically, does the bus speed limit the CPU upgrade? Would it be worth going to a 2ghz or would it not be any faster?

    Cheers

    Specs:
    MacBook: 2GHz, 2GB RAM, 120GB HD; PowerTower Pro (300MHz G3 clone): 608MB RAM, 10GB HD
    Even with system bus bottleneck a 2GHz processor will be faster than a 1.5GHz processor. However, I don't think it would be worth throwing money at. If you absolutely must have more speed than a 1.5 GHz G4, I'd save my $$ for a G5 or a new intel mac.

    that helps me too thanks guys i am new to macs, but i know in the pc world if you dont have the fsb to go with the cpu you are just making a bottleneck mess and you will dissapointed with your machine when it does only an little better.

    Yes. The bus speed does in fact limit the overall speed of the computer. You can go with a faster CPU but it's just never going to get that much better than you have now. I used to have one of those machines and the bus speed was what made me decide to get a new machine after i went the route you have. Right now your machine is a bout as good as it's ever going to get and you probably would not have seen a large performance gap if you had chosen a 1ghz CPU instead.

    Imac 27", i7 3.5GHz, 3TB Fusion drive, 32GB memory, macOS Sierra.
    Years ago also had a Gigabit Ethernet upgraded with a Powerlogix CPU upgrade to run leopard. Was okay but very limited. Save your pennies for a Mac Pro/
