I'm currently on a tight budget with my first PC build, and I'm in a dilemma on whether to downgrade my CPU or GPU to buy other parts, so I need opinions on whether I should have an i5-6600 with a GTX 1070, or an i7-6700 with a GTX 980. Keep in mind that this PC will be used for mainly gaming, with a few bits of video editing, and I'm not overclocking my setup.
