Okay i know that with crossfire when second card is in x8 second slot below x16 first slot it cuts the first slot bandwidth and makes it run at x8, so my question is, is it better to run crossfire in x16/x4 slots? does the bandwidth of the first x16 slot gets cut when x4 slot is used for second card instead of x8 slot? im asking this because my pcie slots are x16 (which in my case is cut to x8 by crossfire) x8 second slot, x4 third and x8 forth slot, will the bandwidth of the first slot be reduced if i use x4 slot or the last x8 slot? i know it is reduced to x8 when i use the second slot, im looking to space my cards to get better cooling but also looking to keep best performance.
