    Hey all, first time poster... I have an old sawtooth G4 (400mhz) that has since been upgraded to 1ghz. Are there or will there be G5 upgrades available for the G4 based computers. There are G4 upgrades available for G3s so I figure I'd inquire.

    As it stands, I am not even close being able to run the new Civ 4 game. :mad:

    Thanks!

    No. The PPC 970--aka G5--must be custom-matched at the factory to its cooling unit and delivered to the assembly line as a module. Apple engineers designed the cases for the Power Mac G5, the iMac G5, the Xserve G5 to accommodate the PPC 970/cooling unit modules. The case of the G4 cannnot be retrofitted to accommodate these modules.

    Also, there are no G5-based Macs with plastic cases. I will give your three guesses why.

    Too bad... What do you think the ceiling is for the G4 based chips and will these make their way into the processor upgrade market? There is one 2ghz on the market (that I know of) as of now.. Thanks!

    ..Or perhaps there may be lower power (less heat) G5's in the future that could work in a G4 like setting..

    G4s are basically G3s with vector units. There are no major architectural changes between then. G5s are completely new chips from the ground up. The FSB difference between the G4 and the G5 chips and the totally different bus signalling used means that it's more or less impossible to put a G5 on a G4 logic board. Even if it were possible the G5 would be crippled by the bus speed. Note this is nothing to do with heat. It's like trying to run an AMD Athlon on an Intel Pentium IV motherboard. It won't work!

    There is also a diminishing return with faster and faster G4s as they too are getting bus starved. You might be able to get a G4 faster than 2Ghz but it will spend much of it's time idle waiting for data to come over the slow bus.

    As more people upgrade to newer Macs (which seem to be getting cheaper all the time) there will be less profit in upgrades so I personally don't seem many more being made for G4 era machines. 2Ghz might be as good as it ever gets for them.

    I guess its time to relegate the beast to music server and pony up for a 'new' computer.. Whats a good buy for a used mac? I prefer desktops...

    How much are you willing to spend? For the same price as many used Macs a brand-new CoreDuo Mac Mini offers a lot of bang for your buck but is very limited in terms of upgradability.

    Other than that dual processor (or dual core) G5s are probably the way to go, although waiting till the Intel towers are launched might be a good idea as these will almost certainly drive down G5 prices.

    I wouldn't recommend a Mini if he wants to play Civilization IV.

    That's probably a good call...

    While your point is valid, I would doubt it to be the case. If he wants to upgrade a 1 Ghz G4 or get a used G5, then it is not likely that playing that game is on his list of requirements.

    It seems like everything is always about games here.

    Also, check the refurb section of http://store.apple.com (Look for the Red Sale tag in the right navigation). There are some real good deals on iMacs right now.

    Wait till WWDC at this point maybe you will be able to get a 64bit for the same price.
