My city's Apple store finally got 1 G5 display model in and i used it for about 2 hours. It was a 1.6GHz model with 256MB of RAM. I helped a few customers (note: I do not work at the Apple Store, but people seem to ask me for my opinion/help anyways) do some various benchmarks and performence comparisons (Xbench, Photoshop tests, etc.) and answered their questions. But, on my own, it was incredible. The thing is so much faster than every other mac Ive ever used. Even the dual 1.42 doesnt really compare, because there is no dual processor integration matters that hinder a bit of the performence. This is super smooth, even with 256MB (the base minimum anyone should really have on their computer, in my opinion). Of course, when a ton of apps are open and active, then performence takes a hit, but it would be incredible to see that machine with over a gigabyte of RAM. So, incase you were wondering, the G5's were definitely worth every second we waited. If the lowest end model can be that fast, imagine what the dual 2GHz can do?!
