    90w single 6 pin and 3x displayport.. But does it work in yosemite? if so i found my new baby for $150..Hopefully the measly 90w tdp will not cause the expansion fans to roar.

    It will work, just use the last official Nvidia webdrivers, the GTX 950 uses the same GPU as the GTX 960: the GM206 chip. The PCI Fan will spin up at first use; just force it too go 100% (Macs Fan Control app) and then let it readjust itself automatically.

    It's such a weak card though. You might as well spend a little more and get something is much faster. It only gets about 50FPS in the PC version of Tomb Raider at 1080p. That means in a Mac it will get about 30FPS. That's a waste of time. If you want a card just for 2D even the GT120 is good enough.

    thing is i use 3 1440p displays and i do not game. i need something that can take advantage of metal and have 3x displayports. Ive been using a gt120 with a 5770 to power the displays. But the 5770 would over heat with little effort and all other cards would be annoying with the pcie fans except the 750 ti because i assume its draws so little power from the power supply.

    A GTX680 can be found for a little more and is almost three times as fast on the Mac. It has the outputs and probably Metal support. We don't know much about how Metal is going to perform yet.

    id get a 970/980/ti if it wasn't for the fans. I know theres all types of solutions but im a shutdown computer type of person and having to run like heaven or some program gets annoying. Im thinking of just getting 2 750tis that run on slot power i know for sure those keep mac fans quiet.

    I don't think this issue affects everyone.

    What about the fans? My 980 is quiet. Heck, the fans don't even move at all when the card is idle. EVGA had to include a brightly colored note telling customers that this was normal, and no, your fans aren't broken.

    im talking about the pcie exspansion fans on the mac pro itself. Allot of mac pros have this problem. You have the perfect mac pro this doesn't apply to you haha the gpu fan itself i could care less about.

    My PCIe fan does not run fast at all with my GTX 650. It remains at 800 rpms unless I benchmark the GPU.

    If you install the GPU in Slot 2 instead of Slot 1, then fanspeed remains at 800 rpms. If using slot 1, then PCIe fan behavior is erratic until you stress the GPU. Then the PCIe fan will settle down. Using Slot 2 is the 'workaround' to avoid that erratic fanspeed completely.
    If your card blocks access to Slot 3, and you need to use SLot 3, then use have no choice but to use Slot 1 for GPU.

    With my GTX 680 or GTX 980, the expansion slot fan stays at 800rpm under normal desktop use.

    My GTX 680 has EFI firmware. My GTX 980 does not. I used both in slot 1.

    As far as I know, no one has been able to find any consistencies to determine which Mac Pros are affected and which are not.

    Ah I see, for me this works but I read up upon it and there are a lot of mixed experiences.

    I am using a 5.1 with GTX 680 4GB flashed with public Mac EFI and before that a GTX 660 2GB, both made the fans behave in the same way (go to 100% and they balance out automatically at stock 800RPM afterwards).

    That didn't change with me, the TS was asking about the PCI/Expansion Fan behaviour. But ok.

    Yeah the GTX 950; mediocre card for too high a price (GTX 960 is roughly the same price, better choice IMO). Would work in a Mac Pro.

    I got a good deal on a gtx 950, but the nvdia driver wont install. It wants el cap 15g1108 and I have el cap 15g1004. I don't see any osx updates in app store. Do I need to install the latest itunes to get this version number?

    Ok, I found a security patch to install, I will see if that does it.

    They need to match. Don't do new updates until a new driver is available.

    There is a good list here:

    Thanks. I installed the security patch and the os build number increased and I was able to install the nvidia drivers. Didn't get a card yet, but at least its ready for when I do.
