Don't get the 1600X... just get the 1600. OC's just as well and includes a decent cooler. Here's a copy-paste from a response I made on another thread...
I strongly believe that the Ryzen 5 1600 invalidates just about any i5 right now. The only case you can make for an Intel i5 is if you're prepared to pay a little more for a 7600K, OC it as far as you can, and game at 1080P on a 144hz or higher display with a very high end GPU (really only 1080ti right now)... AND, you only care about current games and performance right now. A Ryzen 5 1600 is cheaper, and with cheaper mobos it can be OC'd to 3.8-3.9Ghz on the bundled cooler... saving even more cash because the 7600K requires you to buy one.
For example, you can get a Ryzen 5 1600 @ 3.8-3.9Ghz with a motherboard on the bundled cooler for $290 right now.
By the time you get an overclockable mobo and cheap cooler, an i5 7600K comes in at over $350
You can make the Intel platform cheaper by abandoning overclocking, but once you do that, the Ryzen 5 1600 (@3.8Ghz) will at least match, and probably beat a locked i5 7500 across a broad array of games. And that's right now, before much optimisation has taken place and with no eyes to the future. Also, if you're on a 1070 or slower GPU, the difference between Ryzen and Intel disappears in just about every title.
The other issue with the i5s arises when you consider the CPU usage and 1%/0.1% lows we are seeing in a number of titles. We're already seeing a number of games where the lows on i5s are not good, well under half the average frame rates, while Ryzen CPUs with their extra cores and threads don't suffer (look at games like
Total War: Warhammer and
Metro Last Light in
THIS review). Also, if you look at the CPU usage of an i5 in a demanding title you'll see all cores pegged in the 90s... there is no more headroom on those CPUs. Those sporadic frame rate dips on i5s suggest that there are already edge cases where they can't keep up. Right now they're few and far between and generally speaking not a real problem, but if future games become more CPU demanding, i5s have nothing more to give. They're maxed out.
Of course, as well, as soon as you consider anything threaded outside of gaming Ryzen 5s utterly demolish any i5.
