This is my 3rd Mac, my first two were imacs that screens had issues. I had each for less than a week. Anyhow, I bought my mac book about 16 months ago. It doesnt power on, and its been determined logic board is issue. Now I am a firm believer in life that you either have to buy the extended warranty on everything always or never...Pick a side....That said, Ive never bought an extended warranty although seeing two bad screens and talking down the apple guy on the price I bought apple care. Anyhow, looks like they would have replaced for free anyhow so technically I question if the apple care was worth it. I have two fast questions If the Nvidia card has issues are they putting in a different part into my notebook, or the same batch of fail cards? I game a lot my notebook gets hot could have this caused it? For how long are they going to be replacing cards post 3 years?
