I have Hp dc7800 Convertible Mini-tower. I want to buy Evga 550ti SC graphic card. I know that my motherboard has the pci-e x16 slot but the graphic card has dual-width size and the motherboard is BTX. I want to know if this graphic card can be fit or not. Any help will be appreciated! Here is the picture of my pcie-e slot.
