Will a PCIe 3.0 card work in a PCIe x16 slot?

[UserZero]

Specifically, I have a Gigabyte p35 ds3p mobo, with PCIe X16 slots (x16 and x4).

I found a silent graphics card - ASUS Graphics Cards HD7750-DCSL-1GD5 - but it's PCIe 3.0. As far as I can tell visually, the edge connector looks compatible.

Anyone know if this will work, even in a 'degraded' mode?

TIA!

All PCIe 3.0 cards work with older mobos that have PCIe 2.0 and PCIe 1.0.
