    i'm debugging a problem system, a first gen mac pro, that has a 7300gt
    in it. i also have a second gen mac pro that has no problems. i've
    made many changes to the problem system and am coming down to my last
    couple of options, one of which is swapping graphics cards. the problem
    system is running an nvidia card, the problem-free box is running an ati
    card. maybe a driver conflict in the nvidia driver?

    the issue is that, on boot, my external sata box hangs when recognizing
    the box's four channels. this does not happen on the second gen mac pro.

    i'm down to the last three things:

    graphics chipset differences
    logic board differences between first, second gen
    osx 10.4 vs osx 10.5

    i'm now testing the graphics card as a possible solution. i've gotten
    conflicting reports as to what graphics cards might work with a first
    gen mac pro still running 10.4.11.

    a tech told me that the 2600xt i have in my second gen will not work
    in the first gen. on the other hand, someone on apple discussions said
    they were using one. will the 10.4.11 system have any necessary drivers
    for this card?

    also, the 3870 has been recommended. i've also thought about the 4870.
    i've also seen a lot of discussion about driver problems (that they're
    unavailable) with regard to the 4870, that the drivers would be included
    in a 10.5.7 update. if these drivers won't be available until 10.5.7,
    it would seem i should stay away from the 4870 for now. but what about
    the 3870? will my 10.4.11 system be able to use this card?

    any info much appreciated,

    10.5.7 is out, and comes with the drivers you need. The 4870 card works perfectly in my September 2006 Mac Pro 1,1.

    That tech is wrong. The HD2600 XT works fine in first-gen Mac Pros - I ran one for several months. Both the 3870 and 4870 will also work.

    I can second this.

    Have a 2600XT that works fine in my first Gen.

    Why Nvidia choose to write separate EFI64 ROMs instead of ATI's universal EBC format is a very good question.

    The ATI 3870 Mac&PC works very well. I would recommend to upgrade the stock 1 slot cooler for something with more oumph, like Vortexx Neo.
