Yeah, well Intel kind of pulled a d*ck move by gimping not only the 6 core CPU, but also the 8 core. One has to spend $1K to get a fully functional HEDT CPU - used to be that ~$600 got one there. Add to that the poor decision on the TIM (it's going to cost Intel sales) and I'm not surprised that people are changing their minds. Why even build a crippled hexacore HEDT system when CFL is coming soon with six cores at a mainstream price??
If Intel goes to 8 cores with Ice Lake, the low end of HEDT will probably be all but lost (unless Intel gets rid of the 'K' line, so that overclockers need HEDT motherboards and 'X' CPUs for maximum overclockering). DDR4 does a great job feeding an 8 core CPU w/two channels, so there really isn't any need for quad channel memory (unless one needs 8 DIMMS to support larger amounts of DRAM).
I guess we live in interesting times
