Will a graphics cards which uses a PCIe 2.0 slot work in a PCIe x16 slot?

Question

I have an old (4 years) computer with a PCI express x16 slot, I was wondering if a 512MB NVIDIA GeForce 8800 GT (which uses PCI express 2.0) would work with it. I don't mind if it doesn't work to it's maximum capability, because I'm sure it would be better than the 128MB graphics card which it currently has.

Answer 1

it should be ok

PCIe 2.0 is backward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and v1.0. In some cases it is possible that a PCI-E 2.0 card will not work correctly on a PCI-E 1.0a slot. This is only limited to certain video cards

Answer 2

Yes, though most call it 'PCI -E 2.0'

Answer 3

yes will work, but the max out put will be 256mb not 512mb. Still better and faster then a 128
