    Specs say 2 x 16X in diual config both run in 8x. Thre is little difference in 8x to 16x as far as performance. You don't use all the bandwidth so 8x works just as good.

    The 2 x PCIE 16x runs in 8x in dual config, the others run in 4x.


    Edit:



    I see yours has 1 x 16x so you would be 16x and 4x. my bad

    It's not ideal for CrossFire. Not saying it won't work...
