Default PCI 3.0 compatibility

Are PCI Express 3.0 cards backwards compatible with PCI 2.0 motherboards? I read a few reviews that say they are but some say they have trouble.

A quality card "should" be because the spec says they should.

However, for this to work, both the board and the card need to be in-spec.

There is more out-of-spec hardware then in-spec hardware.

Make of this what you will.

I have a PCI-E 3.0 GTX 660 card in a 2.0 motherboard if that means anything. The data bandwidth is practically the same, even under heavy loads of gaming. You will not see a difference.

It'll work. I have a PCI express 3.0 GTX670 graphics card and my motherboard is only PCI express 2.0. No issues.

New standards are "almost" always backwards compatible with their older ones. USB 3.0 will work with USB 2.0 and so will PCI-e 3.0 with 2.0!
"Laws that forbid the carrying of arms...disarm only those who are neither inclined nor determined to commit crimes. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than prevent homicides, for an unarmed man may be attacked with greater confidence than an armed one.
