    Hey there, after upgrading from Mavericks to Yosemite, I encountered a significant drop in overall performance with my gigabyte gtx 560. Nvidia drivers doesn't work (its stuck on grey screen upon restart). Would really appreciate if someone could suggest a noob tutorial or give me an advice how to make this card run faster with some tweaks or something! Thank you!

    Your post is confusing, are you saying it doesn't work at all or has poor performance? You should probably post in the sticky thread at top of page.

    FWIW, I happened to try some 560 cards last night in Yosemite and they didn't work.

    Yup, Im running native yosemite drivers and it is laggy, like with the GT120 which comes with 2009 mac pro. To be honest I was using the wrong DVI port it seems when I tried it with NVIDIA drivers, thats why it was showing a white screen upon startup. Still Im confused, because the same card was working fine running Mavericks native drivers.
