I use both Première Pro and FCPX (so I am asking a similar question on the PP forum). As I only have 16GB so going to 32GB is a no brainier. I was thinking of going to a 6th gen 4Ghz CPU but have been advised it is not worth it. May go to a i7-3770K and over-clock. My goal is to be able to edit 4k more smoothly. I can just about edit 4k prores proxy but GH4 camera files are too much, but I think I would need a dual socket Motherboard and a couple of 4Ghz CPUs to do this, but beyond my budget (I think).
So if I think I wont upgrade the CPU/Motherboard the graphics card seems the best option. Now PP supports OpenCL (and because I also use FCPX) I am thinking a AMD card. My Motherboard has two full sized PCIx slots but only one is 16*, the other is 4*. Was wondering if 4x was actually any use, could get a couple of AMD cards, wondering if it is worth it and which cards to get. My current PSU is a 550 and only have 2 power connectors for GPU (both currently used) so may need to upgrade this.
Wondering what cards to get. Could afforn around 250 pounds (maybe a bit more), may get used.
