I need a new Apple Computer. I want to use my external monitor, so it could be a small laptop or a mini. My minimum specs are and I 5 processor 2.6 GHz, upgradable to 16 gigabytes of RAM. It needs to be able to run Final Cut Pro. I'm asking the question under this forum, because I am uncertain how well the integrated graphics of the Mini would perform. How expensive would an acceptable external graphics card be? Thanks in advance for your consideration.
