Interesting subject. What's your budget? That's the main thing i guess. What CPU are you using with your motherboard, not that I would recommend changing that anyways, hopefully it's a i7 anyways.
The graphicscard i guess it's a bit of an issue. GTX 760 with 2gb vram for grades and nodes isn't overkill. I sould defenitely say that SSD's like Samsung EVO or Pro 850 in Raid 0 is way overkill. One big like 1-2tb is enough. But shure you get higher reading write and read speed but that's not crucial. I say that the Premiere Pro with CDNG files is an issue and that your GPU aswell is an issue. Have you tried Davinci Resolve?
My budget is around 600 euros for SSDs, GPU and RAM memory uppgrade; that is around 200 euros for each of these upgrades. Yes I use i7 processor (6 core) and 16 GB RAM (upgradable to 32 GB).
I am using a Asus GeForce GTX 760 but I can add another graphic card to my MSI Z87-G45 motherboard.
I tried uploading davinci resolve but found it very hard to find use and no tutorial to help me use the databse (media storage) properly. FOr isntance, I wanted to use davinci only for rendering since many claim that it is better than Pr/AE. I created an XML proect file from my finished Pr project file and imported it into davinci 11. However, it didn't open all the associated files. Don't know what the problem is and looked for solution on the internet without any result. Hence, I uninstalled the software and using Pr CC2015 (with imports and supports cDNG natively).
