Mid-2010s Kernel Panic GPU - best options? I'm having issues with kernel panics on a mid-2010 Macbook Pro 15 inch. I have read many threads about this (What&#39;s the cause of GPU panics on macbook pro mid 2010?) and the thread that links to are good examples. The panics seem to be related to GPU/especially video for me. Mavericks made them less frequent, but they didn't go away.

Apple was able to tell me that the logic board has already been replaced (before the computer came into my hands, presumably as part of the extended warranty that was intended to fix this problem). 

Given the age of my computer, I'm wondering what my best options are. Is a new graphics card certain to fix the problem? If so, is it best to send it to Apple or to try to order one and install it myself?
Suggested problem tracing /and repair) steps (after each test the performances).


Vacuum clean the inside of your Mac to improve cooling.
Google and Install gfxCardStatus, Leave on Dynamic Switching. From there it will Monitor and Alert you to what apps switch you to the Nvidia Graphic Card.
Also open the Activity monitor - Energy tab, where you can see when the Nvida card kicks in, and does it switch on/off irregularly.
Monitor your Console log for irregular (fast)GPU switching.
Do some hardware testing: 



  GpuTest is a cross-platform (Windows, Linux and Max OS X) GPU stress
  test and OpenGL benchmark. GpuTest comes with several GPU tests
  including some popular ones from Windows'world (FurMark or TessMark).


This test might help you decide to replace the card.
