I'm looking to purchase the PNY GeForce GTX 770, it is a PCI-Express 3.0 x16 card so I'm wondering it'll be compatible with the 1.0 PCI-Express x16 slot in my motherboard. Thanks to anyone who leaves a response. <3

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. But that's a separate thing from the PCIe 1.0/2.0/3.0 spec.

Sorry, that's a little abstract. But the tl;dr is that you have...


babachicken is pretty much spot on, considering you only have a 1.0 slot changes are your processor is rather old and will bottleneck the GPU.

Assuming that's accurate, you definitely have a PCIe 3.0 slot. Its part of the compatible chipset, there are no other options.

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.
