The bandwidth will also vary depending on the number of installed card.
My motherboard (Z77 G45), will allow one card to run at 16x bandwidth (pcie 3)
but 2 cards will run at 8x bandwidth
3 cards (using the pci-e 2.0) will make the first cards run at 8x bandwidth and the two other at 4x

What tool do you use to confirm this slow down?

I got this one my MB manual Wink
me too.
However, hwinfo64 show the actual bandwidth used by the card (gpu-z also I think)
