Hello,

maybe this question has been posted before but I can't find any answer.

I know that a PCIe GPU may implement 2.5Gb/s(PCIe 1.1), 5.0Gb/S(PCIe 2.o) or both specifications at the same time. I've read that to work under a PCIe 1.1 mobo, the GPU must incoporate both standards.

However, I've seen some GPU-Z screen shots of the Nvidia 8800GT satting that the bus used is PCIe 2.0. Does this mean that also supports backward PCIe 1.1 even though is not specifically indicated by the manufacturer?

Thanks in advance and sorry about my english

Yes, PCIe 2.0 is fully backward compatible. A PCIe 2.0 video card should drop right into a PCIe 1.1 slot, and work properly. At worst, you may need a BIOS update on your mobo, but even that is doubtful.
