Hello, so, I've ran into an unexpected need for an upgrade yesterday. My father's PC (i5 2500k, GTX 970, 8GB DDR3) no longer performs well enough to quench his Cities Skylines needs. The venerable i5 has finally reached its limits, and he wants an upgrade. Because the current situation with CPU's is a bit pricey (and he doesn't want AMD), I've started looking for a replacement for my i7 6700k, which I intend to give him along with the mobo and RAM (basically he'll pay less this way). Thing is, where to go? I was fully satisfied with my current build (the i7, 16 GB DDR4 and a GTX 1080). What CPU would you recommend? I mostly use my PC for gaming - my job doesn't involve me running power hungry applications. Any help would be greatly appreciated. Thanks in advance.
