So I got a "Sawtooth" from a friend for 20 bucks and I'm wanting to upgrade it to use as a fairly fast (for a G4) deskop. Its specs are as follows: 350 Mhz G4 576 MB PC133 RAM ATI Rage 128 Pro 16 MB VRAM 10 GB Ultra ATA HDD Surprisingly the RAM is more than 512 MB, which is great as it will save me money. So the first component I would like to upgrade is the graphics card. 16 MB of VRAM isn't nearly enough and would like at least 128 MB. I don't want to spend too much, but I'm totally open to recommendations. I can handle the hard drive since that's pretty easy. I do have one question, however: everymac.com states my model can only support up to 128 GB drives. If this is the case, could I easily install a workaround and still rely on my data being safe? So the biggest worry of mine is the processor. 350 MHz is actually a little better than I expected, but I would like a boost while saving money at the same time. What's the highest CPU speed I can get using this logic board? Or do you suggest installing a different logic board (if cheap enough) that supports greater CPUs? I'm totally open to suggestions and am very comfortable with working in open computers. I've done upgrades in the past so I am experienced enough to try difficult tasks. Oh and one more quick question: since this logic board uses USB 1.1, can I still get USB 2.0 speeds if I install a separate PCI card? I appreciate all the help. Thanks in advance!
