Hi, I have an option on a 2012 MBP (base model), for US$750. My needs are not high end; HD video in FCPX sometimes, Photoshop edits occasionally, but a lot of just normal stuff usually. I like the pull-apart upgradeability of the 2012, esp for holding all my files and footage (with a dual drive setup). I am worried about the 512MB VRAM, (wish it was 1GB...), especially looking ahead to a 4K+ future... $750... Worth it? Any advice appreciated.
