I have a 2011 27" iMac with the Core i7. For the second time in less than a year, the video card has died. It was 4 months out of the Apple extension on this warranty issue the first time so it cost me about $600 to fix. Now the replacement video card is dead. So do I spend another $600 plus whatever it cost to replace the existing HDD with a SSD or do I just bite the bullet and get a new one. The one I spec'd would be a 3.2 i5 with a 1TB Fusion and 16 GB Ram. But the buyer's guide is saying Caution on this model. I would guess even going down a processor that this machine would perform better than my old one. Or possibly a refurb with an Nvidia GPU vs. the AMD one that has dies twice. I can get a decent refurb for anywhere between $15-1800 that would be compatible to my current machine. Or go all out and get a Pro even though the buyer's guide has it as a No. Thoughts.
