Dave - I have a Quicksilver 800. The processor isn't too bad, badit's biggest down fall is it does not have the L3 cache that the G4's after it did. I am looking to uograding to either a single 1.4, or a dual 1.25. Any idea which would be a better configuration? Particularly for ArchiCAD?
AC is not dual processor aware, so doesn't directly benefit per se from having them. The benefit comes when you run multiple applications--PlotMaker, etc.--and run multiple tasks concurrently. I rarely do that. If I'm going to photorender an image, I'll do it when going to lunch or I'll catch up on phone calls or some other task away from the computer. It really depends on your work habits. GS says the two most important elements of a system with respect to speed in AC are processor speed and quantity of RAM, and as AC evolves, they will become even more important.
