    I have a mac pro early 2008 running on the latest Yosemite OS and i want to upgrade the original gpu (nvidia geforce 8800 GT) with a new nvidia gpu.

    i have found on my local pc store a lot of new GTX750 ti models for about 120-140euros which is my fine for my budget.

    Will they plug and play if i first install the apropriate *nvidia drivers :
    *as found on this thread :

    or do i need to flash them?

    :)

    Mac EFI firmware will give you boot screen. Without it, they will not show anything until OS X and the video drivers are loaded. Once the drivers are loaded, they work fine.

    It worked fine! I successfully installed a GTX 750 Ti and i am also getting the both OS and nvidia updates!!!!
    The only problem is that a fan kicks in very often and goes extremelly loud.

    I downloaded the macsfancontrol software and i see the following metrics

    CPU_MEM - This goes up high!
    IO - This stays cool
    EXHAUST - This goes up high!
    PS - This stays cool
    *See the attached file

    Does anyone know a safe custom setup for CPU_MEM and EXHAUST to keep the noise down?
