That's because some reballers try to rip people off by reballing the original (and henceforth damaged) GPU back into the logic board.
A new GPU should be reballed to eliminate the problem.
Seems like I have a knack for buying the wrong machine. I went through this with the 2007 MBP and its inherently faulty GPU. At least that one was acknowledged by Apple and repaired for free. Let's hope they do the right thing again.
I've got a 15" 2011 MBP with the AMD 6770, never had any issues with it. Is this something that will happen eventually then?
Just about every 2008 Macbook pro I know of (including mine) ended it's day with a failing graphics card.
I'm happy running a 17 inch 2011 one now and this thread has worried me as I was hopping to make it last many years - I don't hold much hope for Apple doing much to help me in the case of a failure.
Anyone any thoughts on whether gaming might significantly reduce the life of the card?
If that was true we would be seeing a lot more reports of issues and Apple would have taken action a long time ago.
Could be. But other parts in other models also use BGAs and don't have this problem - did Apple magically figure out how to handle the thermals on the other models?

Yep. Me too. 2007 and 2011 for my personal use. 2009 for my wife - that one still running fine to this day (use it as an iTunes server for apple tvs).
The iFixit teardown showed that the thermal paste on the GPU in the 2011 models were applied worse compared to the previous generation ones.
When buying an expensive item from Apple, AppleCare+ is a must.

It helps to finally have Apple stores around in Germany. My top of the line Macbook Pro 15" late 2009 was replaced three times, once via phone support and then twice via store. I finally arrive at the 2011 17" I am still using and had the GPU repaired by a third party service. People might think its fun to get repeated logic board and whole new computer replacements, but when you have to reactivate dozens of software licenses, partly by phone-calls, then it's not exactly a perfect experience.Apple would do fine in Germany where there are virtually no consumer protection rules. Everything they have in favor of consumers has been imposed by that EU, otherwise it's total anarchy for large companies, and courts always rule in favor of the larger subjects. In fact if I buy anything in Germany I usually don't expect any guarantee at all. I will be responsible for repairs from day one, even if the law sort of pretends to keep you protected for a year.
So you're betting Apple that the device will need some sort of hardware-replacement, for which you are paying upfront?
I disagree. I've come across this issue in two cases (one being my own laptop). And simply reflowing the solder has provided quite a decent fix (which I know isnt permanent, but they are both still going strong). This says to me the gpu's are fine, and its simply the solder joints. I do plan to get my macbook pro's gpu reballed with leaded solder (to prevent a re-occurence), but Im not getting a new gpu, as I dont see the point.
Its my understanding, and I could be wrong, that this was quite early in apples move to unleaded solder to comply with newer EU regulations.... And those AMD gpu's ran hot like mofo's. The two didnt mix well.
