The Titan X is, if memory serves correctly here, roughly 10% better than the 980 Ti. It is, however, ~$300 more for it. Is it because it's the best? No, it's because it has 12 gigs of RAM on it, as opposed to the 980 Ti's 6 gigs. The GDDR5 RAM is quite expensive.
As far as CPU's go, I would honestly ask what you plan to use your computer for. If it's mainly for gaming and such, an i5 6600k will be better for you. If you do a lot of music recording/editing, video editing, and other programs that munch CPU up for lunch, then you should aim for an i7 6700k. It's not as big of a number, but the i5 is honestly better for gaming in my opinion.
I used to use an AMD 8350 as my CPU, and it was great, but it ran hot, used a lot of power, and didn't run multiple programs as well as I would have liked. I have since bought an Intel 6700k, and I'm much happier with it (I do music editing, and a little bit of video editing on top of gaming). The 9590 is just a binned 8350. It runs hotter, and uses a LOT more power. Personally, I'd recommend the i5 6600k for you, with a GTX 980 Ti.
