    I have been researching whether or not the Nvidia GTX 770 will work in a 2009 Mac Pro. After some research, I have found that drivers are not the issue, however the power consumption is. I have seen people who have ran the GTX 770 no problem without a external PSU, or any rewiring in the machine, etc.. On the other hand, I have seen people having to run a external PSU for this. What I want to know is, will the Nvidia GTX 770 work perfectly fine without having to replace, rewire, or use an external PSU, etc. in a 2009 Mac Pro. I cannot seem to find a definite answer to this, and this forum is my last resort to find a definite answer.

    My current specs of the 2009 Mac Pro are as followed:

    2.66GHz Xeon
    Nvidia GT120
    640GB HD
    1TB HD

    If any questions arise, I will be happy to answer them.

    Wrong section, but I'll do my best to answer anyway.

    Firstly, you would need a new power supply with 8 + 6 pin PCIE connectors.

    However, this is impractical because a GTX 770 will be bottlenecked by your processor; you won't get maximum performance because your processor can't keep up with it.

    You will be better off buying a new Mac Pro or building your own PC/Hackintosh.

    Agree with DarkSel. You don't want to pair a GTX 770 with an old school processor because the CPU will very much limit the potential of your new graphic card. Please, do yourself a favor, you don't want to run Lamborghini's engine under Toyota's hood.:rolleyes:
