    Hola folks.

    A friend of mine is selling me an EVGA GeForce GTX570 HD 2.5GB card for a reasonable price. I was wanted to verify that this card will work with the Mac 1.1? I read the forums and found a posting that apple applies limits when using video cards greater that 2GB's. :confused:

    Is true about the 2GB limit?

    I am currently running that latest version of Lion with an 8800GT.


    Cheers,

    According to the first page of the Nvidia FAQ here, it should work just fine.

    The 2GB limit is for OpenCL only. If you need OpenCL, follow the steps to fix it, also linked in the Nvidia FAQ.

    If you want this card for CUDA you need to run 64-bit kernel.

    There's a guy in this video installing a GTX570 in his 1.1 Mac Pro to enhance his gaming. HERE Though I read thru his posting and comments, it was not indicated if the 570GTX performed at maximum speed since the 1.1 Mac Pro is still 32bit. And if the vram is 2.5g was not also specified. Probably you may want to ask this guy how's the performance.

    Success

    I was able to install and get the card up and running with a slight hiccup. I f*cked up the CL editing and had to reload the OS from back up.

    My mac is a lot snappier and gaming on boot camp is great. I know the card is still running on PCI 1.0 but i don't care most of the games I'm running do look a lot prettier with the setting and AA turned up.

    Next stop is the CPU's+ SSD.:D
