Hello, I always get confused over how bus lanes work so I want ask the community here about a specific configuration of GPUs on the motherboard regarding one dedicated PhysX card in addition to the normal use GPU. What is the best placement on the bus lanes?
I'd like to put the dedicate PhysX card on the x4 lane so it does not have the x16 lanes going into dual x8 mode. The two cards not being so close and hot is a nice added factor but I'm not sure what would occur if I had it in the 4x lane.
I'm wondering that it would definitely go into x8 dual mode if I had both the PhysX and normal card in the x16 lanes.
I understand that there's much talk over the little improvement over having them in dual but would the x4 slot being used affect the x16 lanes or is it more of a standalone bus lane?
Thanks!
