My G4-450 AGP with 1024 MB seems to be running slower than I remember and I am getting more spinning disc (beach ball) time. Just went to the Apple store and played with the new G5's and gave me a bad case of New-Mac fever until I ask some questions. The new (tower) G5's only have room for one drive and that was a big turn off. Maybe I should consider one of the new after market faster processors. I wonder if I will really see much difference with something less than a 1 GB? Dick
