I bought a sapphire vapor-x r9 270x 2gb ddr5 to upgrade from my GTX 470 which malfunctioned after 4 years of use. I have a Gateway model :FX 4170-UB003A I plugged the card into the PCI Express slot, but it does not detect the card. I installed the drivers with no luck, in device manager it appears as a VGA standard display Is there any problem of compatibility between my motherboard and the video card? If so , I would have to return it
