Shoestring budget upgrade suggestions?

Hey everyone! I recently got a pc with the following components.

GPU: GTX 760

CPU: FX-4100

MB: 970A-UD3

MEMORY: 16GB DDR3 2000 Mhz

PS: 530W

STORAGE: 256 GB SSD

However, I would love to be able to use it for video editing. I am currently on a shoestring budget of less than $200 and wanted to see if there would be any no-brainers to spend this money on.

Thanks!
