Hi all. First post here, so please be kind as I have a lot to ask... In the past I had worked on both a G3 iMac and a G5 PowerMac; I made the transition from PowerPC relatively late in the game got my first MBP in 2010 when i7 came out. So when I received countless kernal panics this year, I was displeased to discover that they were all related to my video card failing from having an external monitor plugged in most of the time. Anyway, I'll be sending off my MBP for AppleCare and plan to get a desktop as well that can handle my workflow. The new MacPro does sound tempting, but no word on when it will come out. The iMac 27" (I want slot loading ram) also sounds interesting as I'll be getting a giant Apple screen with it and won't have to suffer with my old Samsung LCD I got on a boxing day sale in 2009. Some things I'm wondering, but can't find many details on... -Is there a big difference when working with FCP with i7 or Xeon? -Are [will?] the graphics cards [likely?] be interchangeable on the MacPro or iMac? -Any other majors perks to MacPro that can justify the wait time or cost? Pretty much that's it. I know the cosmetic differences and since the updated MacPros aren't even released yet, obviously there's no tech info yet. But if anyone can give me speculative advice, that would be great too. Price is not a HUGE factor, but reliability is more important to me. Thank you.
