I've been researching this issue quite a bit, and it seems that the Inquirer article is probably right. All of the Early 2008 MBPs are doomed to a relatively short life. It takes about a year for the average 8600 GT to fail, and if you don't do a lot of work that causes temperature swings, it could last just long enough to fail after the 2-year warranty has expired. I still have 1.5 years left on Apple's newly extended GPU warranty. So far my MBP is not showing any symptoms (it does have the vertical stripes problem, but that's another issue). What should I do? Should I take it in and see if Apple might just replace the GPU anyway? Should I try to sell the thing now, hoping that the buyer won't care as much as I do about the GPU being doomed? Should I just risk having to pay for a very expensive repair in 18 months or so?
