Ok so I have always been a semi - pro user, I have a powerbook, family imac (high spec) etc. And I was thinking about taking the plunge at a Mac Pro, now I may not need one for my current needs but my powerbook is whining to be laid to rest and the fact that it may last for 4+ years sounds great to me. However since this would be quite a significant purchase for a student I have a few questions to ask first! 1. If say I went for the stock 8800GT in the PCI 2.0 slot and then bought a 2600XT would it have much benefit in final cut express, gaming etc. (i.e. would they work together?) 2. Would the Mac Pro really last long enough to not warrant an upgrade? 3. If I bought the single 2.8 would I be able to add another one at a later date that would work? 4. What other options are there for the PCI slots? 5. If I left the second superdrive open would I be able to put in an HD drive or anything like that? So basically is the super-customisable machine I had been hoping?
