Even Apple is pissed...
As I surmised earlier, nobody is really "safe" with the fixes for these computers with these video cards. Electronista has an article at
http://www.electronista.com/articles/09/05/11/nvidia.sued.over.graphics/ where they point out that Apple and others are suing nVidia and seeking class action status. It acknowledges that owners may get an extra year of warranty from Apple but at the end of that extra year you STILL may have a failure from these bad cards and then (my comment, not theirs) you are screwed.
I know some comments have been made that would imply that only certain cards from a certain date were bad but I don't recall anything that says so definitively. The "solution" for this may be an extra year of Applecare but that would be crap for whatever owner has one of these computers three years down the road. If Apple stated clearly and definitively that current motherboards/cards are all "good" I'd appreciate a reference to that comment as I have a good friend with one of these computers and I need to make recommendations to him to sell it off if current cards are still bad or to keep it if a repaired computer is really and fully fixed. The comments below don't imply that the problem is permanently fixed when a repair is done.
from Electonista we learn....
Although Apple, Dell and HP also tried to find a solution, Apple by promising to repair any defective MacBook Pro for two years after the purchase date and Dell and HP released an update (designed by Nvidia) to increase fan speed to prevent chip failures, the plaintiffs still claim that this is an improper remedy for the problem. The five plaintiffs also believe that the faulty processor can lead to further problems such as degraded battery life, slower system performance, and increased noise. In addition, the fix only ensures that the computer will not fail during the OEMs express warranty period, leaving the longer-term effects to reveal themselves after the warranty.
Currently the lawsuit requests the case be granted class-action status, which could involve millions of laptop computer owners and result in Nvidia having to replace the faulty chips and pay unspecified damages.
