* Please note that the Sapphire Radeon HD 7950 only is compatible with the 'Mid-2010' and 'Mid-2012' Mac Pro models. The other video cards above are compatible with the 'Early 2008' and 'Early 2009' as well as the 'Mid-2010' and 'Mid-2012' Mac Pro models. Over the past several months I've been getting kernel panics due to the graphics card, resulting in my mid-2010 MBP crashing. Change music from wma to mp3. It's been getting progressively worse, something several times a day. A graphics related bug that affected MacBook Pro systems upgraded to OS X 10.7 Lion has resurfaced for a number of people who have upgraded and subsequently updated their systems to Mountain Lion.
But, I could 'invest' $600 to get the old one working and buy myself enough time to get the next generation. Also, fixing it makes it salable so I should be able to get my $600 back. Right now it's a piece of almost worthless junk. My current thought is to invest the $600. Free snipping tool for mac.
Then take note of which extensions your system actually loads with kextstat. Then reboot with previously loaded NVidia/Geforce kexts moved away and the hack enabled. Get a detailed sensor monitor (iStatMenus, TGPro, etc) and watch the temperature on and around the GPU. Now load one after the other of the relevant kexts back into the kernel with sudo kextload /path-to/NVDA***.kext. Wait one or two minutes after each. Since the method of this post – or the equally valid but looong way: manipulating EFIvars in Linux – is NVRAM it will come off cleanly if you do an SMC/NVRAM reset. That NVRAM hacking is actually the only part of this post that for sure will not give you much trouble.
See if falls in this time period. I was asked to replace hard drive in a 2011 MacBookPro after a friend of mine had problems. He picked it up in Florida as a used/refurbished so he WAS not the original owner.

Hi, I'm having some serious problems with my 1 year old MBP mid 2010 (4GB, 2.53 GHZ, Intel Core i5). Last week, it became extremely slow.
I have the famous MacBook Pro 6,2 with GT330m ( 0x0a29 model). I discovered that this problem happens every time that g-state change between 2 to 0. G-States go from 0 to 3, are related to the thresholds inside AppleGraphicsPowerManagement.kext, like this: G-state 0 (maximum speed) and G-state 3 (lowest speed). I solved the problem by keeping it always at G-State 2 (medium speed). And the performance? Exemple: Cinebench, default (G-state 0) i've about 15fps, with g-state 2 (medium speed): 10fps.).

So, I asked her to specify what the problem was with ' my graphics card'. Apparently, they do not have the techinical knowhow (even it went to their factory or some sort of centre) to find out what was wrong with the GPU and all they do is plug in a gadget to test it. This seems like a party line that they have to tow. All in all, I will have to fork out 400pounds to get this fixed. However, I am not going to accept this and am going back to witness the diagnostic test. I would like to arm myself with as much info as possible about this whole NVIDEA saga.
Anyway, for video playback, try IINA. In my experience, that’s better than VLC in MacOS. For GPU commendation, you really need to tell us do you require boot screen. If that’s just preferred, and you have a stock Apple GPU on hand now.
If your video playback is choppy now, that may be still choppy even you upgrade to a TitanX. IMO, the only bet now is Vega. Since the coming iMac Pro will ship with the Xeon that I believe has no iGPU (no Intel QuickSync), and I don’t think Apple can afford the iMac Pro looks stupidly slow in the video encoding test etc. Therefore, they may activate Vega’s dGPU hardware encode / decode ability. For Apple’s style, there is a high chance that we need a Vega has identical Device ID as the iMac Pro’s Vega (or even need some hack) in order to benefit from it. However, it’s still just my guess. Since Apple may only care how the iMac looks but not how it perform, there may be no hardware encode / decode ability at all for the iMac Pro.
