Hi All.... I just picked up a G4 Sawtooth 500Mhz, and added 1.5Gb of RAM and 160Gb if of disk and a Radeon. Interestingly enough it's been pretty cheap so far. Having said that it's time for a new processor. Ive beeing looking at OWC and have seen a few that should do the trick. Now, for the big question... Single or Dual? Looks like I can get a dual for just a bit more than a single, see here; https://eshop.macsales.com/item/PowerLogix/PF47D1200DA/ What are the groups thoughts? 1.2Ghz Dual or 1.8 Single? I use this machine for image editing and I am plannig on doing some iDVD work now. TIA Mike
