Looking into getting a Metal capable card for the upcoming Mohave release and have been looking closely at these two cards. Both are around the $150 price range, albeit one being used (and 5 years old), VS the other being brand new. Id mainly be using the cards for video editing in FCPX, with some light photoshop work. I don't really game at all on my Mac Pro, so that is not a requirement. Anyone have any experience with these cards and could give some insight which would suit my needs better?
