A note on performance: To take full advantage of multiprocessor machines you need to have a strategy for maxing out its resources. This can be seen above in the Processor Single and Processor Multi test results. Also certain applications take better advantage of multi processors than others. Bottom line ... The resources of the Quad machine are huge, however will your workload and work style take advantage of this capacity.

Johnny AppleSpeed's philosophy on computer upgrades ... At a fairly early point, it becomes less cost effective to hold on to an aging machine than to sell it and move on to a newer model.

Hi -
I've got a dual 1ghz G4 PowerMac (with 1gig RAM) (Quicksilver) that I want to replace with the Quad core G5, though I expect to upgrade the video card to the mid-level 7800GT. I'd love to tell the boss I'm working to convince to pay for the new machine how much more performance he'd be getting. I do mostly graphic work - 3D surface modeling in Strata 3D CX, but webwork, Dreamweaver, Fireworks, etc. . .
