Increased zombie spawns to pc requirements

[TreCircuit]

Hello,

 

I am going to be replacing my age old potato pc and part of the parameters in my selection is going to be the ability to have much larger hordes in 7DtD.

 

I have read and tinkered with the increase spawn mods, but my current pc doesn't let me go to far.

 

What are the pc requirements in priority order to be able to handle much larger hordes?

 

My current estimate is CPU threads, RAM, GPU RAM but I don't have any true method to test.

 

Anyone have some high end computers say their specs and how high of hordes the pc was able to handle?

 

Thanks for any input!
