Thanks guys for all the help. PC will be for gaming @60Hz @ 1080p but more so for music production.
The i7 4790K I have does the job for that with the occasional slowdown and stutter depending on load, gaming it runs perfect with my Strix 1060, can run everything maxed out. I was going to upgrade at some stage this year and I'm just worried now about this Intel stuff and slowing down my PC, plus I like the looks of the Z370 AORUS Gaming 7 board
