Is a PCI express 2.0 video card backward compatible with a PCI express x16 motherboard?

Will an 8800 gts pci express 2.0 card word on my m2n-sli deluxe asus motherboard? Says it supports pci express x 16 so is 2.o backwards compatible?|||All of the new graphics cards that support PCIe 2.0 are backward compatible with motherboards that support only PCIe 1.1. BOTH Pcie 2.0 and 1.1 standards USE the x16 PCIe slot.



Actually the new cards would hardly be slowed down by the PCIe 1.1 slot. PCIe 2.0 has a VERY WIDE bandwidth that could hardly be utilized by most single cards. It is the dual or quad GPU set up that would benefit most from PCIe 2.0.|||In short Yes, but at half the bandwidth of 2.0.|||Yes it is backwards compatible. It just won't work as fast as the pci-e 2.0. I have a ATI Radeon 3850 which is pci express 2.0 and it runs on my pci express x16 very well. Good Luck with the video card.|||yes it will work|||Yes, they built the new cards with backwards compatibilty so we don't all have to run out and buy new motherboards too just to use the new cards. It was really smart on their part, with how expensive cards are getting we all don't want to have to drop another couple hundred dollars on a good, new motherboard at the same time just to use a new card.|||backward compatible runs 2.0 cards at half the bandwidth.
