    Hello,

    i'm going to buy a new Mac Pro octo in a few days but i'm still wondering about the graphics cards.

    I definitely need two of them in purpose of running four displays. The second will be a standard GT120.

    What i need now is a fully compatible card that;

    a. can drive two displays (30" and 24")
    b. works without trouble with windows (bootcamp and XP or 7) and OS X
    c. has a good gaming performance (i guess the 4870 is pretty poor with a 30", isn't it?)

    I looked at the 4790, but i heard about difficulties with two monitors.

    Thanks in advance!

    Well, I was going to recommend the TripleHead2Go, but that device's max is two 1900x1200 monitors per DVI port, and you have a 30"...

    Probably your best bet is either a 285 or 4870 with a GT120 - with either card, you would have to use the GT120 (or other earlier low-end card) as two 4870s or 285s, to the best of my knowledge, would draw more power then the PCIe bus could handle.

    285 with injector is a way to go, or Mac's 285

    A flashed XFX 4870 works with both monitors, so long as you plug your 30" into connector 1, and the 24" into connector 2. I have 2 monitors running on mine and they work perfectly. Just make sure to buy the same model listed in the tutorial.

    The Mac 285 is way overprized, so a stock one would be nice.

    So both the 4870 and the 285 will work fine with another GT120?

    The 285 is still twice the price of a 4870, is it worth it?
    I'm no hardcore gamer, just about two hours per month, but games (crysis, cod) should run smooth on a 30".

    Do you plan on using Windows for games? In that case, there is a difference - just look up benchmarks, and decide if the price is right. In OSX, I am not too familiar.

    On the other hand, its been rumor'd up that CUDA will be of use in various applications which calculate embarassingly parallel data - CUDA only exists on the GT120 and 285; however, rumored. If you haven't head of the word, you probably don't need it :p

    Windows will be used for games and 3dsmax, but latter doesn't require much gpu power for my purposes.

    Under OS X my only need for gpu power is Photoshop CS4, apart from that, the cards should just drive my displays. ;)

    CUDA? To be honest with you, never heard. :)

    What about display rotation with current GeForce cards?
    The 6600 in my Quad is'n capable of rotation.
    Is that possible with the 285 and GT120, or limited to ATI cards?
