I just wanna buy one HD 7970 3GB for my 2009 MAC PRO. Do you guys flash the card or does 10.9.2 natively support HD 7970 diver? I've been looked at some HD 7970 cards on ebay, just confused with the power cables, some has one 6 to 6 pin and 6 to 8 pin cables. Others has two 6 to 6 pin cables. I don't know which one to buy is safe.
Here is the link:

Mac Pro, OS X Mavericks (10.9.2)
I think you don't need to care too much about 6pin or 8pin power cable connection.
6pin/8pin pinout of PCI-E power cable connector:
1) +12
2) +12
3) +12
4) GND
5) GND
6) GND
7) GND
8) GND
yes-i agree with what kaz-k has written. As long as you get the correct power cables for your graphics card you should be okay. I think the Mac Pro has 2 6pin sockets. We don't flash the card ( thought I'm assuming it could be done elsewhere) , and Apple doesn't support anything other than a few graphics cards anyways, and it doesn't really read what's been posted here. here's the takeway: The card will probably work, however, due to the lack of a Mac EFI (basically a boot rom), you won't see a startup screen should you choose to install the card into your mac pro 2009. As the OS gets going you will see graphics. Should you need to do basic troubleshooting, eg choosing which drive to start up from
(command R on startup, I believe), the lack of a boot screen could be troublesome. If you don't care about that, by all means go ahead. 10.9.2 should have support for this card. If it helps, I bought a Sapphire 7950 for my Mac Pro 2008 (3,1) and although it doesn't run at quite full speed, it was a breeze to install, and it beat the 8800GT which was in that slot
good luck
