Do you have any suggestion for me for dual setup? (PCIE x16 splitting to 2 PCIE x8 required)
That would work with crossfire? Not that I'm aware of.
I'm not the best person to ask about this, but I don't believe adaptors would work due to the way CrossFire cards communicate with each other through the motherboard.
As suggested you'll be best off looking at a new motherboard which has crossfire support.
What CPU do you have?
