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.
Hey I'm in the same boat here. Trying to squeeze some more 4K power out of my 2010 Mac Pro 5,1 with some upgrades. Does anyone have experience with the.
To see which graphics card is in use, open About this Mac and go to the Displays Tab. To see which Application is using the higher-performance discrete GPU, open Activity Monitor and go to the Energy Tab. I decided to take an early 2009 Mac Pro and see if a GPU upgrade could bring this once beastly computer back to being on top once more. My inspiration came from NVIDIA's announcement for Mac support for their latest and greatest GPU lineup.
When Apple released OS X 10.7 Lion in 2011, a number mid-2010 model MacBook Pro owners found their systems inundated with crashes and graphics-related errors in which the system would show a black screen and freeze, requiring a forced shutdown and restart of the system.

This issue affected a number of people, and because some users were able to overcome the issue with a logic board replacement in their systems, it was suspected of being a hardware-related issue.
Apple eventually issued a software fix for the problem, but this appeared to be more of a workaround than a true fix.
While the software fix has kept this issue relatively silent, it appears in the latest updates to OS X 10.8 may have undone it a bit, causing these systems to experience graphics-related problems again. This time, instead of displaying black screens, the systems are largely experiencing kernel panics where the system's screen fades to gray with a message stating the system will need to be restarted.
The panic reports from these systems show the familiar model identifier 'MacBookPro6,2' (the 15-inch mid-2010 MacBook Pro), and show the last kernel extensions being accessed before the crash as the graphics drivers for the Nvidia GPU. This model information can be looked up by choosing 'About this Mac' from the Apple menu and then clicking the More Info button. In the window that pops up you will see the model name, such as 'MacBook Pro 15-inch, Mid 2010.' Additionally, you can click System Report and see the model identifier in the Hardware section of the report window. The model for affected systems is primarily MacBookPro6,2.
If you are experiencing these crashes on your system after updating OS X to the latest version, the workarounds that helped prevent this issue in the past may still apply now.
Regardless of what you choose to do, one way to help the situation is to report the issue to Apple using its feedback page, and also be sure to submit any crash reports your system generates to Apple. These will help outline the issue so Apple's engineers can address the problem.

Reader Ted Gresham’s older MacBook Pro is misbehaving. He writes:
I have a 2010 15-inch MacBook Pro. I pulled out the DVD drive that I never used and installed an SSD drive. Lately, the MacBook has been crashing—displaying a black screen and then a message that I have to restart. Did installing the SSD drive break my Mac?
No. I’ve seen reports of this happening with this particular model—with and without an SSD installed. The consensus is that the computer’s NVIDIA GeForce GT 330M graphics card is to blame. This MacBook has the ability to switch from high-performance graphics to on-board graphics and switching from one to the other can cause these black screens and kernel panics.
There are a couple of workarounds you can try. The first is to launch System Preferences, choose Energy Saver, and disable the Automatic Graphics Switching option. This causes the MacBook to always run high-performance graphics, which will affect battery life.
You could also try the free gfxCardStatus application. This places a menu in the Mac’s menu bar that allows you to choose one graphics card or the other.

This issue has been acknowledged by Apple in its MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video KnowledgeBase article. For your purposes the most important passage of that article reads: “Apple will service affected 15-inch MacBook Pro computers free of charge until three years from date of purchase.” If it were my laptop, I’d take it in to your local Apple Store or Apple Authorized Dealer (or, if you don’t have a local Apple Store, contact Apple’s support and service folks at 1-800-275-2273 in the U.S.).
The problem doesn’t affect all mid-2010 15-inch MacBook Pros. If you're not Ted and haven't seen this problem with your MacBook Pro then your laptop isn't affected.
