I figured that the new architecture would be much more efficient than the old, but it doesn't seem so. I would like anyones opinion who cares to share. We are thinking of replacing two G5s that have the same clock speeds and ram that comes standard on the latest version of the mac mini. (atleast if the price is right) I purchased one for testing (macmini), but it seems much slower than our old G5s when running similar loads... (CS4,font manager, macffice, and our design software). Any thoughts are much appreciated.
