I ran some of the applications on the machine [system preferences, safari, photoshop, iCal, iSync, Airport Admin, etc.] just to get a "feel" for the responsiveness of the system [for daily, general usage].......
it didn't seem as "fast" as I was hoping [though, I'm sure the dual 2.0ghz is a different story].........
the responsiveness was on par to the latter G4s.
Nothing "extraordinary" I'm afraid.
Some applications opened in one bounce [safari, address book, etc.] but some took multiple bounces to open [system preferences, airport admin, iCal, etc.].....
... I do know that's not the most effective means to measure responsiveness

that's the best reference I could come up with at the moment to measure general system/g5 feedback ....
