I have a Connect3d X1900 XT-X graphics card and a ASUS A8R32-MVP DELUXE motherboard and the question is which PCI-EXPRESS SLOT do i put my graphics card in.The manual says the blue slot for a single card and people are telling me i should have it in the black slot but i told them it only should be in the black slot only if i've got a master card as the manual says or am i missing somehing here
