Depends what games you want to play, at what res, whether you want to OC or stream, and what your ambient (room) temp is.
A 1060 6GB will still handle most games at or near max settings at 1080p, many at 60 FPS. Ryzen is better for streaming though, so if that's an interest, I would wait for the soon to be released Ryzen 3000 series.
As for your parts list, I would not advise getting an OEM CPU, as you won't have more than a week or two warranty at best. With retail box you get 3 years from manufacturer. It's also smarter to get the 6 core i5-8400, which is only $194 retail box, comes with cooler, and is quite a bit more powerful than a 7600. You could even get a retail box 8600k for only $18 more than that 7600, or $31 more if you go with the H7 mentioned below (the better choice by far).
I also advise a better cooler. The Hyper 212 was good in it's day, but the Cryorig H7 for $38 at Newegg, is much better. I'd also step up to a Z370 MB with it's more future ready m.2 support. You'll need one anyway if you go with an 8th gen Intel, but they can be had pretty cheap now.
Lastly, no need for a 750w PSU. not even a 1080 Ti requires that much. You can get a Corsair Tx-M Gold 550w for only $60 at Newegg. At that point between the CPU, Cooler, and PSU, you're saving up to $93, and can afford considering an SSD drive. If you've not bought the GPU or MB yet though, or are still within full refund time, I would go with the option below in the summary.
HOWEVER, it's definitely worth noting if you've not yet purchased the GPU, that a 1070 starts at $300 now, and is a fair bit more powerful than a 1060 6GB. You didn't list a price on MB or GPU, so I figured you already bought those, but wasn't sure. I would highly recommend returning the 1060 if you bought it from a place like Amazon or Newegg less than a month ago though.
Right now Newegg has a dual fan full size 1070 for $300, which if you haven't purchased the 1060 yet or can refund it, could be afforded if you just change the i5-7600 and Hyper 212, to a i5-8400, and the SuperNOVA 750 to the Tx-M 550. The cooler the 8400 comes with is easily good enough at stock clocks, especially if your room temp is average or lower.
This whole build list of yours has some seriously bad choices, which is why it's imperative you ask these questions before buying anything if you're new at it. I recommend signing up for Newegg's email subscriber deals, because quite often they have even better deals than the ones I mentioned.
In summary, for best (non streaming/OCing) raw gaming performance, I recommend the i5-8400 with stock cooler, the Corsair Tx-M 550w, and the Gigabyte 1070 for $300 on rebate. It's a full size GPU too. Just remember you also need to get a Z
370 MB with 8th Gen Intel CPU.
