Custom build help!!!!!

For gaming, this would be better. The 6700K just isn't a good investment, it's $50 more than the 4790K with only a negligable performance increase. At this point, I'd really only suggest a 6700K over a 4790K because you wanted to switch to DDR4 RAM, which you didn't do anyway. The 4690K will be great for gaming, and saves you $100 to put towards a far better power supply than the one you had chosen.
