I have an asrock z97 killer fatal1ty MB with one PCIe 3.0 slot (in use by video card) and several PCIe 2.0 slots.

I want to add a PCIe SSD drive, but most of them are PCIe 3.0. Would PCIe 3.0 SSD work in a PCIe 2.0 slot?

Yes, but it will be severely hampered being a 2.0 slot.

You'll likely see zero difference over a SATA III SSD.
