As much as I love my Powerbook, it appears I'm beginning to outgrow it. I've found the limits of the computer on quite a few occasions over the last couple of months or so and am thinking it's time to buy one of the big boys. I'm thinking of buying a a dual 2.5GHz G5 (200GB, 6800 card, Airport Extreme and possibly 1.5GB Crucial RAM) but wanted to know just how much faster a computer it is when compared to the Powerbook (in particular the 1.33GHz, mine running 1GB RAM). Have any of you taken this step? If so, what have been your thoughts? Also, I've searched quite a lot for good/detailed reviews on the 2.5 G5 but am yet to find any. Can any of you guys point me in the right direction? Thanks! Andy.
