Hi i am building this PC:

I am thinking about CPU and motherboard now because i9 9900k is released and ASrock TAICHI z390.
Other thoughts about CPU is Ryzen 7 2700X but i am not a big fan of AMD.
So… please guide me how to build the PC right. I am strugulling in the web, searching for the real utilization of PP. :slight_smile: Thanks.
