So after having my iMac in 2 different shops over the past 2 weeks, it looks like I have a bad video card. I know there is a recall but I am past the 4 year support period for that unfortunately. Both shops tested the computer for almost a week, and neither were able to reproduced the issue I was having with the computer, as I am a web and UI designer and ask a lot of my computer daily. A new 1gb video card is about $1000 for parts and labor. So after many days of dreading making a decision, I opted to get a refurb'd late 2014 iMac 3.5 i5 retina with Fusion drive. My question is, what is the speed and performance difference between my old computer: mid 2011 3.4 i7 12gb ram 1gb vid card 1tb standard hard drive and my new computer late 2014 3.5 i5 24bg ram (I'm adding 16gb to the existing 8gb with 2 new 8gb dimms) 2gb vid card 1 tb fusion drive Does the more ram in the new computer, along with the fusion drive off-set the i7 vs. the i5? Please help reassure me I made the right decision. So once I sell the old iMac for parts, I am at about the same as I would have been to repair the older computer, at least that was my line of thinking.
