Question Pci 3.0 x4 card at pci 1.0 x16

[deskman1234]

Does a pci 3.0 x4 card works at pci 1.0 x16 motherboard?

I am trying to buy gt 1030 but it is pci 3.0 x4.

Will it work like pci 1.0 x4 and seriously decrease the performance?

First thing you must remember is that the GT 1030 requires a PCI Express slot (not PCI as you seem to think)

There'll be some performance loss if your slots are only first generation.

I saw those are regular pci x16 shape and described as pci e 3.0 x4. Will it work as pci 1.0 x4?

PCIe 3.0 cards are backwards compatible with PCIe 1.0 and PCIe 2.0 slots.

Just remember, however, that a PCIe card will not work in a PCI slot (a PCIe card won't even fit in a PCI slot).
