Can 1.0 cards work in the new 3.0 mobo slot?

[Sonikku]

I seem to be getting conflicting answers on this subject. Some say Pci express 16 is backwards and forwards compatible in all cases. Others report differences in voltage in some variants like 2.1 that results in the breaking of backwards comparability. Others report not being able to get 3.0 cards like a 7750 to work in a 1.0 motherboard slot. So I don't know who is what or where on this case. My pickle is this;

Will my aging X1950XT work in the 3.0 socket of my motherboard without any fiddling until I can get a newer card?

Whatever you use on that mobo will work. Youll just get PCIe 1.0 speeds. which is slow.

Well it's a 1.0 video card, so it would be no change in performance from my older motherboard, correct?

The problems I've seen have been with using newer cards in older motherboards, rather than vice versa. Let us know how it works. Worst case, a card with equivalent performance to the x1950xt would cost about $40-$50.

He's not using a 3.0 card in a 1.0 slot, he's doing the other way around. He's using a 1.0 card in a 3.0 slot. So, he'll be getting exactly the speed that he should.

PCI-E is backwards compatible, isn't it?

The only motherboard chipset + Intel CPU combo that will provide an actual working PCIe 3.0 slot is: Z77 + Ivy Bridge CPU. Therefore, one may get similar quality video by just using the Ivy Bridge's on-CPU Intel HD 4000 video output, and not installing the outdated PCIe 1.0 video card.
