I have stayed on Z97 and not gone to Skylake. I hear the X99 platform whispering in my ear. And the form factor being ATX is a big plus for me. I really want one, have to see if the money can be found to migrate my H440 rig to X99
Despite how good that board looks and how well it performs, I couldn't really justify forking out the expense of building a machine that would comfortably outperform my 4790K.
I'd probably spend half my time playing games and the other being in denial that it was worth it.
