Hello! My situation is the following: I will most likely spend at least one year studying abroad. This is why i figured my 27" iMac would be wasted staying at home and not getting used. Also, i feel my 13" Macbook will not be entirely capable of all the tasks i will have to do. The Machines: 2011 27" Imac, the base model. I did, however, upgrade the Ram to 12 GB. 2012 Macbook Pro, base model. I switched the HDD for an 480 GB OCZ SSD. Both in very good conditions, no dents or anything. The Imac has one dead Pixel. How much do you think is appropriate for either of these Machines? I would like to buy a 15" retina Macbook or a similar Windows Laptop as a replacement and would be thankful for any recommandations here as well. Besides the every day tasks, i will mainly be using it for 3d Stuff like Zbrush, Cinema 4d, Maya, etc. Thank you. EDIT: Also, would you recommend selling now and buying the Retina now or to wait for the update? I will be leaving at the end of august.
