I read that this board does not have a PLX chip that gives you enough lanes to support 2 graphics cards I was thinking of getting another gtx 770 if there is a sale on them and i can get one cheap enough if not i will wait and buy something down the road. I know this MB is SLI and CFX certified but according to a video i saw on this board it will not have enough PCI-E lanes for two GPU's...is this right or am I able to get another card in there???
