OK, so I am ready to take the plunge for a new Mac Pro, but I’m looking for a little clarification on some things before I do. I am trying to decide between the 2.93 Quad and the 2.26 Octo. I am a print graphic designer, so the Adobe Creative Suite is the bulk of my app. work. I may dabble in editing some home movies down the road, but it is not what I do for a living. Some observations/questions from poring through the forum here: 1. The 2.93 Quad would probably provide a greater speed boost in the short term (next 18-24 months) and the 2.26 Octo would be better in the longer run. Does that sound about right? 2. Snow Leopard is going to be a nice boost to the Octo. Does the same hold true for the Quad? 3.The earliest Snow Leopard will be out is June. Is there any reason to think early Nehalum adopters will get a discount on SL? I can be persuaded to wait three months if it means saving $129. 4. I was under the impression that an internal drive couldn't be used as a Time Machine backup, but apparently I was wrong about that. Other than the drive not being "outside the box" as it were, is there any downside to doing this? If the main HD goes down, the others are still OK to just slide out and install in a new machine, right? 5. I learned enough here over the last week that installing my own additional hard drives is the way to go. That said, when I go to sites like OWC and Newegg, I don’t know exactly what I’m looking for. Does any SATA drive slide right into these babies? Well, I’d appreciate any feedback from my questions/comments. I have swung back and forth many times a day between the two models. Considering I’m upgrading from a 9.33 GHz G4, I’m probably splitting hairs, but I want to make my purchase as future proof as possible. Thanks much!
