I am thinking of purchasing a used B/W G3 or G4 Yikes now that Sonnettech has released a 1Ghz processor upgrade for the 2. Which one would be the better buy? The Yikes is more visually appealing (which makes little to no difference but I'm weird like that) but the G3 is generally cheaper to pick up used. Should I just perhaps go a little further and grab a G4 Sawtooth or maybe even a Gigabit Ethernet/Digital Audio? I am on a limited budget and can't afford any more than 12-1500 tops for all parts and upgrades. Don't want an eMac nor an iMac and I am weary about buying a laptop anytime soon (kinda waiting to see how the whole "G5 Powerbook" rumormill pans out and a getting a laptop is not a high priority as all I would use it for is for playing video games during really dull lectures in class).
