Thanks @philipma1587 and @Wotan Wipeout
I have been mining with my 3 cards since december on 3 of my work PC's ( I work as IT tehnician so I can use everything there)
My plan is to get experince of cours, I will be using 3 cards, then adding 1 more and 1 more until 7 eventually if possible, I only want the right components from the start
Also I wanted to go for AMD in case I need to switch from Zec to ETH
What I meainly what to know guys, is if I can run (eventually after experience) 7 GPU on Z87 mpower max OR z97 g45 gaming , AND and if any of those requiered any special bios or smth and where could I get it from
Edit: one more reason for wanting the possibility of 7 is that I don't have much space for multiple rigs, so I need to be as compact as possible in order to put the rig in my office
