Yeah, it's been kicked around a LOT, but I'm in a bit of a different situation (I'm not really focusing on the G5 as an option (I'm cheap).
Currently, I can pick up the following systems:
PowerMac 867 G4
• Dual-867MHz G4
• 256MB PC2100 RAM
• Combo Drive
• 60GB Hard Drive
• MDD Enclosure
• $1299
PowerMac 1GHz G4
• Dual-1GHz G4
• 1GB PC133 RAM
• SuperDrive
• 80GB Hard Drive
• Quicksilver Enclosure
• $1600
PowerMac 1.6GHz G5
• Single-1.6GHz G5
• 256MB PC2700 RAM
• SuperDrive
• 80GB Hard Drive
• New Design
• $1800 (educator discount)
Now, I really do need a SuperDrive, so I'll be adding that into the cost of the dual-867 almost immediately (I can wait a while, but I'd like it as soon as possible). I'll also need a lot of RAM since I'll working only with video projects (just school projects and personal videos, so I'll just be using iMovie and iDVD). I can overclock the dual-867 to 1GHz fairly easily, but I still would have to buy 1GB of RAM to match the dual-1GHz offering; the same applies to the G5 tower. I want the low-end G5, but with a different motherboard than the other two models, I feel as though I may not get the most out of my investment.
What's my best bet of, first and foremost, the two G4 towers, and should I even bother with the G5? Speed isn't a terrible concern, as most programs I use employ SMP, so it's more a question of new architecture than anything.
