Hello,

I'm building a new system and when installing my gigabyte 980 gtx with backplate, as realized that the RAM brackets are blocking to the VGA due to the thickness of the backplate. Therefore I had to use PCIE 2.

I tried removing the backplate, but there are screws from both directions which means I have to take the VGA apart to remove the plate.

Since PCIE 2 is x8, how much performance loss an I looking at?

Thanks!
 
its a X99S XPOWERAC OR X99 XPOWER?, If its the X99S XPOWER connect the card in the third PCI-E it should be x16.

if you are using XPOWERAC connect it in the fourth PCI-E Slot, it should be X16.
 
Either way, absolutely zero performance difference between pci-e 3.0 x16 vs x8.
