The speed increase on an Intel machine running CS3 is immediately noticeable and absolutely worth the price of upgrading.
I have demonstrated to colleagues that the efficiency gains of CS3’s integration and improved file browsing and new roundtrip editing capabilities (ie Dreamweaver to Photoshop) alone take productivity into the red zone.
If you couple these interface-derived efficiencies with the power that comes from marrying CS3 with an Intel chip - for which, of course, it has been optimised - then you have some very real gains to be made.
This, of course, means you can focus more on doing your job better than you did it last week, because instead of wasting time getting a job off the ground, you can focus your time on your creativity.
Once you have CS3 running, you should invite your boss to see just how much more efficient you have become. Of course, he won’t need to visit your desk to do that. You can screencast him using Adobe Connect (part of all CS3 packages) with the new tricks you’ve discovered. Yesterday I attended an Adobe presentation in which the demonstrator was 1000km away, screencasting his CS3 demonstration to our Windows-based network, with the output screened up using a projector. Pretty damn cool. Would have been better if not for network lag.
I have CS2 on a G5 iMac and CS3 on an Intel iMac right here. If it’s merely a speed differential you want, I can run comparisons on identical images running PS filters.
But the real beauty of CS3 is the productivity gains that come from a synergous relationship between the world’s best creativity apps that once belonged in two separate boxes but now come together as one.
