I have an imac G3 400mhz DV model with 256mb of ram and i'm wondering witch operating system would run best. I would like to keep it up to date, but am worred 10.3 might take a speed hit. Would 10.4 have any major advantages over 10.3? Speed? Would 10.2 be significantly faster then 10.3 or 10.4 in things other then startup? Would Safari 1.3.2 (latest safari for 10.3.9) be out of date? I have been told all of these systems would take a speed hit if they are installed over top of the current os 9. Is this true? Any other things i might want to know before installing os x on this model? note: I won't be using dashboard or spotlight.
