If you could only afford one of the following iMac 21.5 2015 options what would it be? They are all pretty close in final price. 21.5 2.8ghz i5 with added 256g SSD (add external drive later on) or 21.5 2.8ghz i5 with added 2TB fusion drive or 21.5 3.1ghz i5 Retina display with 1TD HDD. Could up the RAM from 8 to 16 as well, or do a hybrid of 2 of the above options if had to push the budget, not sure if I need to?? It's to upgrade from my old 2010 MacBook that has done me well, it's for home use, web browsing, some home video editing, Microsoft office, emails, lite gaming, iTunes and home media use. I want to try future prof it as much as I can, be good if I could get another 5-7 years out of it. Cheers guys.
