I'm looking to get a new or refurbished 2013 27" iMac. I'm limited in budget and it looks like I may have to choose between the 1TB Fusion drive and the Upgraded Video Card with 2GB VRAM. I plan to use the iMac for video editing in FCP X as well as some Photoshop and Aperture editing. I use Multi-cam in FCP X. I have a USB 3.0 external HDD for storing video, so I'm wondering if that makes the better video card more important, but I've read that the Fusion drive is amazing. I would love to be able to do both, but I'm already over budget just to get one. Any recommendations? Real world experience would be helpful too. Other useful info: I'm planning to buy the 8GB RAM and upgrade myself when I can afford to, eventually maxing out. I'm currently on a 2008 20" iMac (6GB RAM) that isn't technically supported by FCP X, but it does work. I expect either model to work worlds better than what I'm used to.
