Speculation is that at the very least, they'll work in any 2008 or later Mac Pro (since they have EFI-64), and there's a good chance they'll actually work in 2006 and later Mac Pro's (the Apple/ATI Radeon HD4870 card had both the EFI-64 and EFI-32 support). This site was created in January 2016 to supply the newest AMD graphics drivers to Boot Camp users who run Windows on their Mac. Official AMD PC drivers are not compatible with Mac versions of the graphics cards by default, leaving Boot Camp users stuck with dated and poorly optimized drivers that are not compatible with the latest games. For AMD Radeon™ Graphics, AMD Radeon Pro Graphics, and AMD Processors with Radeon Graphics Only. For use with systems running Microsoft® Windows® 7 or 10 AND equipped with AMD Radeon™ graphics, AMD Radeon Pro graphics, or AMD processors with Radeon graphics. Download and run directly onto the system you want to update. Custom Configuration Mac Pro Video Card Options. At the time of purchase, each Mac Pro could be configured with at least one higher performance video card as an optional upgrade.

It’s been well documented at this point that Lion deactivates the DisplayPort on unofficial 5870 and 5770 cards. (Some 5770s will not run on Lion at all, but some do, including the single slot model.)
Maybe you’ve gone ahead and installed Lion, and are living with the card minus DisplayPort functionality. Or maybe you are holding off on Lion because you depend on DisplayPort for one of your displays.
Hopefully this patch will help. What it does is slightly modify the video driver for these cards, in a way that allows DisplayPort to operate. Unfortunately, only two displays remain operational – in other words, if you have two DVI displays and one DisplayPort display, one of your DVI displays will be knocked offline when you plug in your DisplayPort display.
It’s not a perfect solution. However, this is a working solution for those with one DVI display and one DisplayPort display. (If your only display is DisplayPort, the problem is completing the Lion install itself, as the DisplayPort will be disabled during this process. If you have a back-up video card, you can use that card to install Lion and install the patch.)
