Thanks for the info. We have a 2011 iMac deep in a hospital that is now exhibiting the video card issue in 2017. I was looking to see if it was worth carrying it a mile + out of the hospital to the car and schlep it to Apple. But now we will purchase a new one.
2 month ago I look mine in, they covered the entire cost of the new card and the cost of labour. What’s more is my hdd had a fault, they replaced that as well. The only cost I had was because I wanted to keep the old hdd...
If you need any help let me know..
whether you wanted a hand doing it your self, or what to say to Apple,
Many thanks,
Tim
