    Im Going to be buying a Mac Pro in January, I think even if Nelhanam is not released.

    The Spec i will be getting will be standard config with 2 x 30inch, but with a 8800GT or Higher.
    i would like to use the 2 screens on my wall to this why i came up with these questions.

    i have a few questions about this, (to help ive added a picture below the questions)

    1. How many Power Plugs for graphics cards are in a mac pro/could i add another 8800GT?

    2. Is OSX/Windows Ok with ATI/Nvidia if i cannot have 8800GT?

    3. as you can see by the picture information i will need 3 Resolutions, im thinking of putting 2x2560x1600 on 8800GT & 1280x960, 1920x1080 on 2nd Card will OSX/Windows Be Happy with this Configuration.

    4. im unsure what to use the 3rd,4th screens for but, as i have them i might aswell use them. What Would you use them for in my position? (they can be swived to face me)

    5. What card would you suggest for 3rd,4th that work in OSX,Windows and not conflict with 1st card

    Wall 40inch = 1920x1080
    Wall 28inch = 1280x960
    2 30inch = 2560x1600

    Programs i normally Use are at the same time (expect for CSS,CNC3): Photoshop,Dreamweaver,Flash,Safari,Itunes,quicksilver,Office,CSS,CNC3,adiumx,

    In front of my MacBook Pro
    The Mac Pro won't have a problem with running all the screens, but it will only work with the cards supplied by Apple (nothing else). There are two power plugs on the logic board for graphics cards. You'll need to buy the second 8800GT from Apple's site as the Mac Pro cannot be BTO with 2 (I think). Everything should work well, though you do have a lot of screen space to organize... that can be a pain to do.

    In general, OS X apps should work in a mixed ATI & Nvidia GPU setup. However, last time I checked (on WinXP 32), a mixed GPU setup does not work properly in Windows. System is functional, but only the displays connected to primary card will work.

    Also, you will have the lowest potential for conflicts if you stay with either 2 ATI cards or 2 Nvidia cards.

    Only the games need the 8800GT (or HD3870) and everything else will run fine on the the 2600XT (or future replacement). The 2600XT can power two 2560x1600 displays and the different resolutions shouldn't be an issue.

    Yup. :)
    They will ship internationally. I even called to confirm. :D

    It gets transferred by the US Postal System to the UK postal system, so I don't know how long it takes. :eek:

    OK... One nVidia 8800 GT will support two 30" monitors out of the box (so will the 2600XT), so having two cards will allow you to add an additional two displays. Apple states the machine could have up to eight 30" TFT's but that'll mean you can't install other cards... Despite what everyone else says, if you have the card installed by Apple (at the store), they will supply you with all the necessary connectors, including the additional power leads.

    As far as windows is concerned, you can simply go into the Hardware Monitor and disable the ATI card then windows won't load drivers for it, thus becoming invisible - thought the fan on it will continue to whirl.. don't know would that annoy you or not.
