I intend to use VIRTUALIZATION often and processor performance is a top priority.

I especially desire performance in a SINGLE CORE which is supposedly better on the 4790K but I wonder if the site rankings represent a fluke there. Can any of you confirm?

I would like a 5 year upgrade window so I wonder if there is actually any significant advantage to FUTURE PROOFING. Is there a big feature the 6700k has? So far the most I see there is SSD interfaces but I can provide expansion cards to the standard PCI-e slot if necessary right?

Why would you want a DDR4 MEMORY when the latency is significantly bigger? It might be the largest distinction between processors but I am not sure which is better.

ENERGY EFFICIENCY, TEMPERATURE, and CLOCK POTENTIAL are pretty similar apparently.

I have a similar decision to make when building my sons next gaming PC.

1) Future proofing... either Haswell or Skylake should last 5 years before to gets too slow and needs replacement. SATA 3 on Haswell motherboards is as fast as an SSD. Intel change their socket configuration the way other people change underwear, so everything gets "obsolete" pretty quickly
2) DDR4. Latency is how long you wait for memory to respond. Memory speed is how fast you get the data once latency is over. However, faster and faster memory seems to make less and less difference to actual performance.
3) Overclocking and the silicon lottery. When a new chip goes into production, yield is low, with big variation in chip performance. When an old chip goes out of production, engineers have optimized the process, so many more chips are good enough to be i7, but often sold as less for marketing reasons... So an end of line 4790k will more probably be a good overclocker than a new 6700k.
4) which CPU is best suited for virtualisation - I don't know

In 5 years time, they will both be running at the same speed as when you buy them this year. Haswell and Skylake will both be outclassed by the latest whizzy processors, and both incompatible with the latest GPU or SSD or whatever.
So no difference..

For my recent build I stuck with Haswell because it uses same memory as all the other PCs in my house.
