Ok - so my 2013 iMac is getting pretty old. The new version of Premiere Pro beachballs all over the place... especially since I upgraded the System OS and from Premiere CC 2017. SUX. I was really hoping for a new iMac today... Oh well. I still need a new edit machine... so I'm wondering what you all think would be the best option for running Premiere Pro CC 2018 version? #1 Refurbished 2017 iMac, #2 new Mac-Mini with Blackmagic eGPU, #3 Macbook Pro with with Blackmagic eGPU? Seems like #1 will end up cheapest and should be viable for editing 4K on a HD timeline? #2 maybe same price for 8th generation chip (vs 7th)? But is Blackmagic eGPU all that great? From the few reviews I've seen then answer is no. #3 would be nice as my laptop is pretty old too... but too $$$ and prob not as much umph as the 2017 iMac? Or is FCPX sooo much faster that I shoudl just finally learn it and keep my 2013 iMac? Help.
