I am going to recycle my 6990 cards until the Furyx2 cards come out. Considering an intel 750 (over 950pro as I can WC it) or recycle and old revox2 drive... so PCIe lanes and and card placement needs to be considered.

So with a dual GPU single card solution does it use 16 pcie lanes in slot one or 32? Would two dual GPUs single cards run x16x16 or x16x8x8x8?

As this board has a switch for pcie slots does it mater what slots I use at all? Or by turning off slots I can use any slots I like?
