    What kind of G4 is it? Is it a "Yikes!" machine (PCI graphics, ZIF CPU socket) or a "Sawtooth" machine? (AGP graphics)?

    If it's a PCI machine, you can't upgrade it to a dual anything. Fastest you can go is a 1GHz G3 or G4, and I'd recommend a G3 (they're faster for non-AltiVec optimized applications... which is most everything. Or was, last I checked.)

    If it's an AGP machine, you can (if you can find a used dual 1ghz sawtooth-compatible card). You can definitely upgrade to dual 1.6s or 1.8s. However, for what it would cost, it wouldn't be worth it. The cheapest new dually card is a dual 1.6 for $380 at OWC.

    Adding a decent CPU won't do you any good without a decent amount of RAM-BARE MINIMUM is 1GB, ideally you'd go all the way to two... Tack another $200 for 4 low-density 512mb SDRAM sticks, if you haven't upgraded already.

    And even then, your graphics card (if you still have the stock rage 128) won't support any of the accelerated graphics (quartz extreme, core image), which means you'll need to pay up for a decent one. Assuming you don't want to flash one yourself, or gamble on a pre-flashed card from ebay, figure another $130 for a barely passable radeon 9200 from OWC.

    Now you're up over $700. Plus shipping. For a machine that may not run Leopard (depending on how it's coded... minimum requirements include an 800MHz G4, but the installer may see that you have a Sawtooth board and refuse to install, even with dual 1.6s), and which will struggle to reach 2/3 the performance of a new, base model Mini with a 2GB RAM upgrade.

    So basically... IF the machine can be upgraded (check it out and let us know what model it is), it's still not going to be cost effective to do so. And while that doesn't necessarily mean you shouldn't do it-I'm currently looking at upgrades for my DA G4-it does mean that you need to seriously consider other options, unless you're doing this for fun like I am.

    see i dont have the money to buy a newer g5 intel or **** even a dual g4, i figured maybe i could upgrade it peice by peice. Im trying to get away from windows, and i just bought the computer above for $81 after shipping, w/o hdd, but i have one to go in it. If i find out i can do all of my software development with java on the mac with out a problem i was going to start upgrading starting with the cpu.

    I'll post some recommendations on how to upgrade that machine if you like, in the morning, but I want to get this up so you can consider it before I go to bed. You'd be a LOT better off getting rid of that machine and getting a newer G4 than you would be trying to upgrade that. You can resell that thing for what you paid for it (or close), and an AGP G4 is a MUCH more capable machine and not very much more expensive.
    This one has 10hrs left... Seller has 100% positive feedback, no DOA guarantee that I see but it appears to be working. It's a very good deal with the amount of RAM it has in it. Your best upgrade right now would be to buy this machine:

    If you look in the back of your Mac, you see the audio Jacks below the USB ports? Are the Jacks Side by Side or one on top of the other?

    Check pics at this URL.

    oh and you can find deals on motherboards and dual g4 cpu's on ebay, i'v found 4 cpu's so far all below 90 dollars, and found a mobo slightly better then the one thats in the current system for 25, just hope theres good deals like this whenever i get ready to upgrade my only problem is i dont know if those parts will fit, i mean are all cpu boards and mobo built the same with the holes in the same places or what?

    Ok let us know. That is one way to ID the machine and tell if it's a Yikes PCI or Sawtooth AGP.

    Did you get it from Ebay? If so do you have the URL of the one you bought?

    1 32-bit 66 MHz PCI (filled)


    im assuming thats the video card slot since the audio is onboard, so i would think that is a yikes pci? since it also doesn't say anything about a agp slot?

    Yes that would spell out Yikes. I have that same machine. 400G4, 16 Meg 64Bit PCI Video. Upgraded mine to 1GB RAM. It's ok for VERY BASIC stuff. You can upgrade it like Geeky said, but the Sawtooth with AGP and even more RAM capacity and the possibility for Dual CPU's would be better.

    What all you want to do with that Mac? Just learn OSX?

    well for starters the reason i went with the cheapest mac i could find that wasn't outdated to bad is i want to experiment with web development, if i can develope software for the web with out a problem then i want to slowly upgrade that mac for suitable standards, 1gb ram, slightly better VC, probably put some more hard drives in it, and im hoping i can upgrade the cpu and mobo after all that im going to save up to buy a dual g5

    i just did alittle bit more research, i found a website that sells the yikes cpu upgrade to a 1ghz g4 for 100 bucks, and i think i wont be able to upgrade the mobo because of the horizontal and vertical audio in/out, atleast i will be able to run sun java studio creator, hopefully. if anyone has any ideas please let me know

    Have you opened it to verify that it's a sawtooth? If it is, the heatsink on the CPU will be very large and the board will look like this (sorry if this is really basic, I don't know what your knowledge of the inner workings of computers is, I mean no offense at all ):
    http://cgi.ebay.com/Apple-G4-Logic-B...QQcmdZViewItem
    Note that the top (rightmost) slot on the left side of the pic is brown and set farther back on the board than the other 3 white slots. That'd be an AGP slot.

    Compare that to a G3/G4 Yikes! board (which, unfortunately, is pictured from a different perspective):
    http://cgi.ebay.com/Apple-Macintosh-...QQcmdZViewItem
    The leftmost slot on the right side of the pic is white like the other 3, and the front edge lines up with the other 3 as well. The CPU heatsink (silver thing at the back of the pic) is also very small.

    As far as upgrades go, take a look at this post and see if it helps you at all. I posted it in another sawtooth upgrade thread last night:
