what??? on a board that only has PCIe 1.0?
3 PCI Express x1, 1 PCI Express x16 are the available expansion slots sorry kind of a noob on computers.
Oh, I see the confusion. All of your slots conform to the PCIe 3.0 standard. But there are a couple different kinds of PCIe slots on a modern mobo. You have x1 slots (really little, short slots) that are for expansion cards such as sound cards, and x16 slots (big slot) that are for high-performance video cards. That number refers to the number of PCIe "lanes" that slot has access to, and becomes very important if you have multiple video cards installed.
Sorry, that's a little abstract. But the tl;dr is that you have PCIe 3.0 and a modern system and you have nothing to worry about. Enjoy your new card and great performance.
