I need a Macbook Pro with a dedicated gbu for film school. I have last gens 680MX iMac so it doesn't have to be completely over the top, I'd just like something with a dedicated graphics card and right now the only one that has that is the highest end one which is way too much money considering I have this desktop already. I'm considering going refurbished for maybe a retina with the 650 1GB. Is it worth it? Are the computers reliable and do they come with new casing/a new battery? I know last gen's retina's had some screen problems. I'm seeing refurbs that were released in Feb of this year. Was that batch fixed or did they still have the issue? I know this has probably been asked 1000 times but it seems search is disabled.
