I have a budget pc with an amd a6 6400k processor, and I want to get an r7 240 2gb videocard. The card is PCIe3.0, so is the hole on my motherboard where I have to put the gpu in. But I red that PCIe3.0 is only supported by FM2+ cpu's, and I have FM2 (not +). Neither do I have a PCIe2.0 slot. What do I do?
