As someone who's really enthusiastic about CPUs, but not at all about gaming (we have things called "workstation" and "playstation" for a reason) I'm really pending towards AMD in the x86 space, because they have some really interesting parts in their EPYC line (and some pretty amazing deals in their APUs). Having said that, if x86 compatibility is not my goal, POWER9 also looks pretty cool too, as do all the ARM-based server chips that popped up recently. I also find the LinuxONE Community Cloud machines to be very interesting (I just wish I could have a zSeries of my own in a 19" server tower chassis). It's really sad the desktop or deskside workstation market these days is mostly x86. It's boring.
