The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '17 CPUPro]

The Intel Core i3-4160 is a dual-core four threaded 4th generation (Haswell) processor. It was released in Q3 2014 and scores a respectable 91 for effective speed. With its base frequency of 3.6 GHz, the 4160 is fast enough to run the vast majority of applications smoothly and it’s very reasonably priced for its performance which make it a sensible choice even when considering building a gaming PC. Although the integrated Intel HD Graphics 4400 are absolutely fine for general desktop use such as web browsing and word processing they may bottleneck a gaming machine. A 20% price premium would buy the slightly older i3-4350 which has a 33% larger (4MB) cache but its only about 1% faster (full comparison here). Overall the i3-4160 represents the best value for money I have seen outside Intel's Pentium and Celeron range of CPUs. [Nov '14 CPUPro]
