Planning a GPU rig

planning on building a few rigs now.

I plan on 6x AMD 480 MSI per mainboard.

any recommendations on the CPU or RAM in general ?

Will I need more RAM then when mining bitcoin or ethereum or does it matter at all ( as long as I can run the mining OS)?

System ram won’t matter, 4gb should do. Go with cheapest CPU option also.

Check out h97 asrock anniversary edition for good 6 gpu mobo

Thank you. I still wondered if it wouldn’t make sense to add a strong multicore CPU anyway since I can mine with them as well?
