Hello, I have a 15'' early 2011 MBP. It has had many graphics issues and extreme slowness since November, a few months out of my extended Apple Care. Apple Care was extremely generous in covering my $550 logic board replacement as I never had issues with my MBP in the 3 years prior(never used Apple Care). My local store replaced it and after a day, the graphics card failed AGAIN! So I took it back and it was sent to Apple Care's HQ in Texas and both the logic board and RAM was replaced. Got it back and it runs slower than ever and still has many graphics issues. It is nearly unusable at this point. I am a student on a tight budget and was hoping this computer would last me a lot longer than 3 years considering it costs over $2000+. I am extremely frustrated at this point, having gone to the Apple Store over 10 times, and being behind on school assignments. I just want this solved. I've read that many 2011 MBP's have had a failed graphics card but Apple has refused to acknowledge this. Is there any other reason I could be having these issues? One tech told me it may be software.
