Will a PCI 3.0 card work in a PCI 3.0 x16 motherboard?

I'm not sure whether my motherboard can use a PCI 3.0 Nvidia 770 because it only has a PCI 3.0 X16 slot

Well that would be the correct PCI-E slot so what is the problem?

The x16 doesn't change the fact that it is PCIe 3.0. It will run in that slot, the x16 just tells you how much of the total bandwidth it will be running at (x16=100%, x8=50%, etc.)

I was really just wondering because I thought compatibility was quite strict but apparently its not really so thanks for the input.

PCIe is also backwards compatible i.e. a PCIe 3.0 card will work in 2.0 and 1.0 slots, and a 1.0 or 2.0 will work in a 3.0. The only thing you cant do is put a full length (x16) card into a shorter (x1) slot or put a PCIe card into a PCI slot, or a PCI card into a PCIe slot. Hope this wasn't too confusing!
