@Hatter - I'm quite familiar with the GTX 6xx series, and have looked at the GTX 680, but I specifically have four Radeon HD 7970 graphics cards, and I'm just extremely disappointed/outraged that I spent the amount of money that I have spent on buying an Apple product (an Apple Mac Pro) and I can't even get a decent top-of-the-line commercial (off the shelf) graphics card to work.
It's extremely sad that Apple can't even take the time to add graphics drivers for a decent graphics card like the Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G).
This thread is NOT about NVIDIA graphics cards. This thread is about the Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics cards, and adding drivers for these graphics cards to OS X 10.8.2 Mountain Lion.
I want to use a Radeon HD 7970 graphics card (with 3GB of DDR5 memory). I'm just asking for graphics drivers to support the graphics cards that I have purchased. That is all. The cards work great in Windows Vista, Windows 7, and Windows 8.
The only problem I am having is with OS X 10.8.x Mountain Lion.
Windows drivers exist. Linux drivers exist. I'm just asking Apple to add Radeon 7970 graphics drivers for OS X to Mountain Lion 10.8.2. I didn't realize that I would have to STOP BUYING APPLE PRODUCTS just to get a decent graphics card and a decent computer. I spent quite a bit of money on my four Apple Mac Pro's (about 3 times more than a comparable PC product) and I just find it extremely troublesome (and TERRIBLE) that I can't even use a standard commercial off the shelf (COTS) Graphics card like the Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics cards, and find it hard to believe that nobody at Apple has the brains (or foresight) to add graphics driver support to OS X 10.8.x Mountain Lion, so that users can actually use a standard Radeon HD 7970 reference design graphics card.
The 2008 Apple Mac Pro used Diamond Radeon HD 2600XT graphics cards. The later Apple Mac Pro's used standard Diamond Radeon graphics cards.
I just find it hard to believe that Apple is falling apart, and can't even keep up (and is about 2-5 years behind the PC sector) when it comes to adding hardware support for the Apple Mac.
Apple Mac Pro's don't even have Blu-Ray support. Although some have managed to find ways to get Blu-Ray to partially work, but you can't watch Blu-Ray movies (or 3D Blu-Ray movies) with a Mac (in OS X 10.8.x Mountain Lion) and also you can't burn or rip Blu-Ray movies in OS X.
An Apple Mac Pro should come STANDARD with a Lite-on Blu-Ray burner (as a standard drive), and should have 3D Blu-Ray support (for watching 3D Blu-Ray movies) right out of the box, and it should also have support for editing/burning/ripping Blu-Ray movies (right out of the box). Apple should pull their head out of their "5th point of contact" and add hardware support for the LG WH14NS40 Blu-Ray burner, and also add support for the Diamond Radeon HD 7970 GHz Edition graphics cards.
The Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics cards are the latest and greatest, and that is what I expect from Apple.
If Apple can't deliver a decent product anymore, and I can't even use decent COTS (commercial off the shelf) hardware then I'll probably have to just put my 2012 Apple Mac Pro on e-bay, and dump it, and just go out and buy a PC (that can whip the **** out of my Apple Mac Pro at nearly 1/3 the price) and can outperform the Apple Mac Pro in nearly every way (including the ability to watch/rip/record Blu-Ray movies, and the ability to use "top of the line" graphics cards like the Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G)
If I spend "top dollar" purchasing an overpriced Apple Mac Pro product, then I expect a decent "top of the line" graphics card, specifically the Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics cards to WORK with the Apple Mac Pro.
I didn't realize that I would need to use a graphics card from 3-5 years ago, and I expect to be able to use standard off-the-shelf hardware with the Apple Mac Pro.
It would be extremely easy for Apple to just take the time, and add Graphics Drivers support for the Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics cards to OS X 10.8.2 Mountain Lion.
The latest operating system should support the latest hardware. I wish Apple would begin listening to it's customers, instead of just ignoring customers, and forcing us to spend/waste thousands of dollars buying overpriced Apple products, only to find out that we can't even use a top-of-the-line graphics card like the Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics cards in OS X 10.8.2 Mountain Lion.
The cards work fine in my Apple Mac Pro (under Windows Vista, Windows 7, and Windows 8). The only problem I am having is graphics drivers support under OS X 10.8.2 Mountain Lion.
Dear Apple,
Could you please add hardware/graphics driver support for Diamond Radeon HD 7970 GHz Edition (7970PE53GHZ) and Diamond Radeon HD 7970 (7970PE53G) graphics card support to OS X Mountain Lion 10.8.x
Thank-you,
