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 i3-4360 is a good value dual-core four threaded Haswell processor. Released in Q2 2014 the i3-4360 is a slightly improved (+100 MHz base clock) version of the Haswell i3-4340. The 4360 is fast - scoring an effective speed of 93. It has 4 MB of cache and a high base frequency of 3.7 GHz which is fast enough to run all but the most demanding multi-threaded applications and games without even breaking a sweat. However, the integrated Intel HD Graphics 4600 will limit the 3D gaming experience. For more intensive multi-core applications, it is worth considering the i5-4690 or i7-4790 (or their respective unlocked "K" versions) which are also refreshed Haswell processors. [Nov '14 CPUPro]
