    I picked up an EVGA gtx 770 4gb last weekend at a local Frys. Here's the card I got on Newegg:
    EVGA 04G-P4-3776-KR GeForce GTX 770 4GB 256-Bit GDDR5 PCI Express 3.0 SLI Support FTW 4GB Dual w/ EVGA ACX Cooler Video Card

    It has worked flawlessly, on both my mac and in bootcamp Win 7. Very quiet too. The EFI has not been flashed, though I know it's possible as there are a couple of vendors selling flashed cards on ebay. Right now, I'm trying to save that $200 and use it unflashed. I have an old gt 120 card which does not require additional power, which I can use in case I need to have startup screen access and boot into another drive. Right now, I'm using a utility called Bootchamp in OS X to boot into windows, but the Startup Disk in the preference panel does the same thing.

    Mac or Hackintosh?

    arrived at this point i have a doubt:
    keep my Mac Pro and buy a Gtx780, or sell it for a hackintosh.
    Help me understand the pros and the cons.

    My Mac Pro:
    2x 2,26
    32gb ram
    ssd 128+ 2x hd 1T
    Randeon 5770
    Usb 3.0

    Personally, I'd stick with a 680 GTX or a 760; the 770 and 780 use more than 225w.

    I got the 680 GTX Mac Edition for my 5,1 and it works beautifully.

    I'm on a Mac Pro 5,1 running 10.9.2 with Nvidia Web Drivers and Cuda 5.4.7. My Video Card is an overclocked Gigabyte GTX 780 flashed by MVC and running on internal power. No issues here.

    There is no logic to selling and building a mackintosh

    Your machine is an 8 core that can be upgraded in both video cards, CPU, and RAM. You can drive 4k video with that machine. If you do a CPU upgrade to faster 12core, depending on what you spend you can double your geekbench score and even push it up towards the 27-32k range, at the top limit of the most expensive new nMP trashcans

    Hackintosh means you are in the world of keeping up with drivers, etc in a maintenance spiral. And not even cheaper.

    Generally, you don't have to install the drivers. You only need to do so to enable CUDA support.

    You can download the CUDA drivers for OS X here:

    CUDA drivers are available for 10.7/10.8 and 10.9.

    I went the Hackintosh route, £1200 bought me an i7 Sandybridge 2700k running 3.5 GHz overclockable to 4.5GHz, 16 GB RAM, 2 x 250GB Mushkin SSD, a Palit Jetstream 4 GB GTX 770 in a really nice case with quiet fans and an Asus P67 Sabretooth motherboard.
    It is running Mountain Lion 10.8.5, once set up drivers and patching are not an issue, just don't update blindly, solid, stable and never crashes, just like my Mac Pro 3,1. I will consider upgrading to Mavericks when 10.10 is released but until then I am in no hurry to mess with it.

    Having said that I wouldn't chop your 4,1 in just yet, it is plenty upgradable and should keep you happy for a good few years. Enjoy the GTX 770 they are fantastic cards. :D

    ^^^^The RAM was probably not seated correctly or there may have been some dust in the last two bank 1 slots. Clean out all your RAM slots.

    Your machine will not run 1333 MHz RAM at full speed without a firmware upgrade and without a CPU change to CPUs that will recognize and run RAM at the faster speed. Your current E5520s are rated to only run RAM @ 1066 MHz.

    I'm thinking of upgrading my mac pro 2010 with the same video card.

    How did you connect the power? Doens't the card have 6pin+8pin?
    Is it safe to use just 6pin to 8pin adaptor in power consumption?
