I posted this in the imac section but then figured this is probably a better place. I am looking into getting a baseline late 2012 21.5 imac. i will be doing some light editing on fcpx, basically just a short film or music video here and there. nothing to fancy. would the baseline be sufficient for this or would any upgrades be strongly recommended? i only have about $1800 to spend so i dont want to purchase anything additional unless it's going to be a significant improvement for what i am doing. thank you.
