I am interested in the new Mac Mini and want to use it to edit videos in FCP. I currently have an older 2013 27" iMac 3.4 i5 Haswell. It has the 2GB GPU. I was thinking about getting the 6-core i7 Mini. Would I notice a difference in performance? I am unsure since it has integrated graphics. When I try to edit video on my 2013 iMac I get the spinning beachball constantly, which is so annoying. Thanks for any advice.
