Capture can double the load in both CPU and GPU.
So that alone could get you most of the way to 60.
But load times are a combination of CPU, RAM and disk speed. Are you on SSD yet? It's time given that 480GB and slightly more cheap drives are now under 99 bucks here and there.
The i5 is fine until you told me you do capture.
So I've been cramming information into my skull for a long while, and I understand in which ways I can upgrade my pc and what they will "technically" do for me, but what in real terms? How do I shorten my Skyrim loading screens? How do I get 60+ frames in 1080p? How can my Fallout 4 quit bogging down to load textures mid game? I have a GTX 970, an Intel I5, an Elgato capture card, and plenty of RAM and VRAM.
