Planning on building a PC right now and I have a GTX 1070 8GB mini, I plan on keeping things to about 1440p, give or take, and i'm looking for the best "bang for your buck" cpu to go with that, cost is a factor, but I would also like to future-proof as much as possible. Should I get the i5-7600k for about $220 or the i7 7700k for about $320? Is it worth the extra hundred and help me future proof or will it just be diminishing returns? or go for something else entirely? Keep in mind that I don't care much about frame-rates, as long as they are 60 or above I don't care about them that much.
