Okay so I opened up my mac pro, and I realized there's 2 of these 6 pin things. And I tried connecting it to the 960, and it fits. Am I missing something here? Do I still need those power cables?

Yes. Either of those cables will work. We didn't know your current video card had these.
Sorry I probably should've mentioned it I just assumed it didn't come with one. Thanks so much for all the help!
I've updated some of the language to make this clearer, particularly in the first question.
Thank you. The updates definitely make it clearer what does and doesn't work (for those of us who aren't experts).
C'mon dude, it's in the OP:
9) I use Boot Camp a lot. How do I switch OSes without a boot screen?
Sorry is this has been covered somewhere, but before I spend any cash I'd like to be 100% certain. If my understanding is correct, this seems to be saying that I can use more or less (given the power requirements and exceptions listed in the original post) any NVIDIA graphics card on my Mac Pro 3.1, is this correct?
Thanks a lot

Yes, with a guideline: Keep away from the super cheap ones; Anything in the x50 - x90 range is your target. e.g. GT610 = trash; GTX750 = good.
Hi Guys, quick question: Does anyone know of a program that you can use in OS X El-Capitan to monitor the GPU temperature? I tried running heaven and the GPU itself worked flawlessly, however, heaven was stuck between 32-33 degrees celsius which was obviously a lie.

MacPros are unable to read the sensor on a graphics card, so no, there's no easy way.
You could install FakeSMC with plugins which would essentially mean turning your MacPro in a hackintosh. This would give you access to the temperature readings.

Quick stub of a post for now, will update later when physically at machine.
Mac Pro 4,1 w/GT970. Yosemite installed, Nvidia drivers installed. Primarily have been running machine in Win7.
Have some work coming up that led me to try using Migration Assistant to complete cloning prior 10.9 setup data over to the 10.10 boot drive. Had to interrupt MA, a normal and expected part of using MA.
Next time I reseated the stock 120 and selected the 10.10 boot drive, the Apple startup shows and the boot screen drops into the black screen with blinking bar cursor.
As I recall from this thread this likely means that MA has overwritten or disabled the Nvidia drivers, is that correct? What, if any, is the command line info I need to enter?
My next step otherwise will be to pull the 970 and try to boot to either 10.9 or 10.10 to complete MA and reinstall the web drivers.

Looks like Nvidia updated the web drivers today (10/6/15). I originally installed a PNY GTX 970 along with an original GT 120 (for boot screen El Cap and Win10) and found that I can't really run both cards at the same time with my three monitors. Lots of kernel panics and restarts so now I'm just running the GTX 970 (capable of driving all three 27" 1080p monitors). Anyone else experiencing the same issues? Any success stories?

Prior to 10.11, how was the functionality of the GTX 9XX series used along with a GT 120 or similar Mac card?^^^^Here's the link:

Looks like El Cap has serious issues when two video cards are connected and you have monitors attached to them. Both PC and Mac cards are having problems. Here's a long discussion about the problem: https://discussions.apple.com/thread/7252069

I have a question! I've recently purchased a GTX 970 for my Mac Pro (not installed yet, waiting for a PCIE power cable from eBay), and I wanted to keep the GT 120 connected and attached to a monitor via VGA for boot screen and OS selection.
Will Windows 10 have conflicting drivers between both cards? I have tried hard to prevent Windows updating the GT 120 drivers, to be able to install latest drivers for GTX 970, but I've not succeeded.
What will happen on Windows 10 when both cards are connected? I know that on OSX there are no problems (at least not on Yosemite), but I think that Windows drivers will conflict.
Nvidia has removed support for the GT120/9400 from their drivers in the summer of 2014. If you install the two cards above Windows will always attempt to install old drivers for the GT120 that disable the GTX 970.
I figured something like that, but given that I don't need the GT 120 for anything but boot screens and updating OSX drivers when needed, can't I just tell Windows to just ignore it?
In earlier versions of Windows you could.
There is one solution, but I haven't seen anyone try it yet.
After Windows installs the driver for the GT120 (it will actually install as a 9400), delete the driver in Device Manager and uninstall Nvidia apps that may have been installed.
There is an admin utility that Microsoft has for download that allows you to disable an update but only after that update has been installed and uninstalled. It prevents further attempts to install it again. Find more info on the following two links:

https://support.microsoft.com/en-us/kb/3073930?utm_source=twitter
If it works, you will then have the GT120 installed using software acceleration only. Now you will be able to install the GTX 970 and newer Nvidia drivers for use as your primary card.
I've tried this method already, now that I'm still safe because the other card is a Radeon HD5770, but Windows keeps installing the GT120 driver (in my case it says that it's a 9500 GT). I think Windows 10 is a bit "too Smart"...
Hi,
Have read the first post, installed the most recent drivers and placed the graphics card in the pie slot and two power cables from the board to the card (and checked for a tight connection.
BUT
i'm getting a blank screen on startup and my comp doesn't seem to recognize the card, a "Zotac Geforce gtx 760 nvidia"card
below are some relevant screenshots that i hope help someone help me?!
thanks in advance!!!

I don't know if this has been asked already, but I cannot seem to get sound out of my GeForce GTX 760 when running under OSX. My monitor is a cinema display, and the audio works just fine when plugged into my Macbook. Only when my MacPro is hooked up do I not hear any sound from it. Also, I do not have this problem in Windows mode, only MacOSX. Is audio support not concluded in the NV driver or is audio not supported for non-EFI compatible GPUs? Thanks.
