I want to crossfire two AMD R9 290Xs and as everyone knows they produce a lot of heat. But what i wanted to know is if I mount one in the FIRST graphics slot, SKIP A SLOT and mount another in the THIRD slot and crossfire them will it run the same as mounting each one in a slot right after another. and my reason for this is that I have a side panel fan and i want to get air in between them for better cooling.
