I'll try to give as much information as possible...


My Mac Pro currently has an ATY Radeon X1900 to run a 30 inch monitor. It seems the graphics card is done. I tried 2 other monitors connected to it and neither worked. I would like to confirm the graphics card is the problem before I buy a new one. I have a GeForce 6800 Ultra in a non-Intel mac. Can I put that in my Mac Pro to test it?


If I need a new card... I found the ATI Radeon HD 5870, but it costs $479.00


Just wondering what my other options would be so I can price compare. I could go with a card for a 23" monitor, but I love my 30" and it still works well.

    The 5770 is just as good and $249. In fact the 5870 would be a waste in a Mac Pro 2,1 over 90% of the time.


    All cards can support 2 x 30-inch, all DVI out ports, and MiniDisplay Ports with proper dual-link.

    RE: Mac Pro Replacement Graphics cards


    1) Apple brand cards,

    2) "sold in the Apple store" cards, and

    3) "Mac Edition" cards ...


    ... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:


    1) Apple brand cards:

    • Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5

    • Apple-firmware 5870, about US$450


    2) "sold in the Apple store" cards

    • NVIDIA Quadro 4000, about US$1200

    • NVIDIA Quadro 5000, about US$2500


    3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:

    • SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1

    • EVGA GTX 680 Mac Edition, about US$600


    The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.




    If you are Meet ALL of these:

    • running 10.8.3 or later AND

    • don't care about "no boot screens" etc AND

    • can re-wire or otherwise "work out" the power cabling, THEN:


    You can use many more cards, even most "PC-only cards"

    Thank you. The list I found said that card was good for mid 2010 and mid 2012 models. Your list shows 2009 as well. Mine is a 2007 (Original). If the 5770 will work for me I'll order it today :)


    I am running 10.6.8... will add that to my profile sig.
