can PCI-E x16 2.0 graphics cards be used in PCI-E x16 1.0 slots?

My dad swears up and down that it will work, in fact he just went to micro center to pick one up but im not so sure, I was always under the assumption that PCI-E slots were backwards compatable not forward.

    The 1.1, 2.0, 2.1, 3.0 are all compatible both backward and forward. Though the 2.0 card is capable of more bandwidth than the 1.1 slot will provide, you won't see any difference. There fore you could use the newest 3.0 cards in a 1.1 slot...OR...a 1.1 card in a 3.0 slot! Bandwidth really effects your video when you are using more that one video card. but not much on a single card.. you will not "see" any difference.
