Hi, I have already asked this question in the apple community FCPX forum and someone suggested asking here too. I have been using my 2013 Macbook Air top spec and max RAM for video editing, which is OK, but rendering is often very slow, when using the canon 5D and gopro camera. There was a suggestion that and recent mac pro or iMac would provide great performance, What do people here think? I was wondering about secondhand Mac pro's rather than iMac as I already have a 30" screen. I would be very grateful for any suggestions of which of the older models would give me better performance than my air?? Also is this a sensible option?
