The 1.6ghz G5 is not a good buy. Its a fast computer, thats for sure, but not only can it not carry the amount of RAM the other G5s can (4GB vs 8GB) but also its RAM is not as fast as the RAM from the other G5s. In addition it doesn't have the PCI X slots, and the dual G4 1.4 outperforms it in many ways. I understand most people wont need that much RAM, but how is this machine going to age well if it has a 64 bit processor without the 4GB barrier being broken. Trust me, the 1.6G5 will devalue fast. I would wait for the 2nd generation G5s to come out. This will push down the price on the current G5 line. And, if you still cant afford any of the biggies, try and find a single 1.8G5. That is a MUCH MUCH better buy, simply because other than not having 2 processors, its components are the same as the top of the line G5s.
