Yes, Though I would get 16 GBs of Ram cause 8 GB is kinda of the norm now and your processor kinda sucks. I mean its about the same as an AMD FX 8350 and you save a hell of a lot of cash going with an AMD setup. If you going to get something more powerful than AMD than I am all for Intel but its pointless to pay out your ass for the same thing. I'd try and get an i7 if you can afford it otherwise go AMD. Also I really recommend a Noctua Heatsink, you might be able to get away with overclocking the Core i5-6600K beyond what an AMD could do with one. Remember if you change from Intel to AMD that you need to change the motherboard as well, overall the specs you listed are decent. How much are you paying for it if you don't mind me asking?
The skylake i5-6600 is not similar to the AMD chip you've posted, it is infact much better than what you have suggested it compares to. Either way, it is irrelevant for his gaming purposes and will not pose any issues. Clockspeed =/= how good a processor is.
