I'm a Web Designer and I decided to sell my PC desktop and buy a Macbook Pro because my job is demanding one. I'm between these 2 refurbished models: Mid 2012 - $1,469.00 Late 2013 - $1,529.00 The 2012 has better price, dedicated GPU, better processor. The 2013 has higher cost, integrated GPU, a bit lower processor. You can get a better look in those Apple Store links. The thing I'm worried about is screen ghosting in the 2012 version or any other hardware issue that's been improved in the 2013 version, or if there a no big differences at all. Do you think it's worth it? Also, I like a dedicated GPU for casual gaming, that's why I'm liking the 2012 more. Thanks!
