I am looking into buying a tower, but with all the hype about the G5, it's hard to separate fact from fiction. Here's what I'm going to do. I need to install MySQL, PHP, and run my home web site from the tower. I would also use iTunes and Office v.X. I have a few games I also play, but those seem more video card related. When I am trying to compare the two different tower models, I really like the power of the G5, but is it necessary? 64-bit computing is just entering the high-end enterprise market with any real force, and most apps are still 32-bit. And PCI-X? I haven't seen anyone requiring 64-bit 133Mhz PCI bus speeds at home. Actually, I don't see many people even use the expansion slots much anymore, especially since video cards are AGP now. I like computing power as much as the next guy, but with the cost of a new dual G4 tower at $1799 and the dual G5 at $3000, what is the extra $1200 gaining me? Even with playing the latest games, I don't see any advantage.
