With mobile annihilating the mainstream PC industry, Intel knows gaming is buttering its bread. The chip giant launched its sixth-generation "Skylake" desktop processors today with two enthusiast quad-core models: the Core i7-6700K and i5-6600K. The 14-nanometer chips are unlocked for maximum overclocking (all the "K" series CPUs will be), and if you're not into that, the two new chips have fairly high base frequencies: 4.0GHz for the Core i7-6700K and 3.5GHz for the i5-6600K. Compared to similar current-gen models, prices are reasonable -- suggested retail is $350 for the i7-6700K and $243 for the i5-6600K, with street prices likely lower.
I agree, it is pricey. But, if you use a less expensive motherboard, case, power supply, hard drive, and other PC parts, and use onboard sound and video on the Intel CPU, you maybe able to build a fast computer for a decent price like $700.
Some people save money by buying a more affordable motherboard, so they stay on budget when building a more affordable Gaming PC, and usually spend the extra money they save on a better CPU, and video card.
I think a lot of people don't need the more advance features on more expensive motherboards like Built-in Wifi, onboard video chips, and Bluetooth if they just plan on building a Gaming PC.
