What pc specs can you recomend for a 8k resolution project?

Hi there, I want to make a project in 8k resolution with Harmony Premium. Does anyone have experience with Harmony and especially the specs of the pc? How much memory, videocard etc? I want to use 2 4k monitors.
I have seen the specs Toonboom recommend, but they are too general. Hopefully one of you have some hands on experience.
