if you go intel id pick 8600 over the 7600 but at the current price of an 8600 if your not into high refresh rate gaming a r7 1700 is going for the price a 8600k is , I feel at this point games using more cores is inevitable as even Intel has move up there core count this year. if you are doing just 60hz monitors i myself would probably get ryzen but if you want to do above 60hz like a 120hz display intels i5 would probably edge it out in cpu bound games as a majority of them care more about single core power then bunches of threads
