Hi so i have been a huge fan of the 17 inch macbook pro with matte display and eventually got the chance of ordering a one used but in great condition off ebay few days ago. However, not until the order was placed do I come across of countless articles online stating the design flaw within 2011 macbook pros, which cause gpu failure. So here are my concerns: 1) does the gpu failure problem frequently occur on late 2011 17 inch macbook pro based on information from macrumors users? (The seller is reputable and he claims the machine is perfect during his testing. I believe him but am still worried when the issue will occur once i have the laptop. #timebomb) 2)Since Apple's repair program ends at the end of the year (2016), does it mean i will get charged for replacing the logic board after that time? Any 17 inch mac users are kind enough to share some of their experiences? thanks in advance !
