I'm trying to get a G4 Tower. I wondering what to start off with either a G4-450DP or G4-450Sawtooth, as far as upgrade ability and cost of upgrades. I have been using Macs a long time now, I just need to upgrade from my G3 iMac. I'm on a tight budget and need to buy low and upgrade in pieces. For now any G4 450+ would be just fine. Wondering if spending $200 extra for the Dual Processor is worth it? Both machines have DVD-Ram one thing I will like, close to same size harddrives, but only a slight difference in RAM, which I can add as I need it. DP has Gigabit and the 450 Single doesn't. So basically from what I can tell, they are pretty much equal except the DP. Any comments? or Ideas?
