Thank you. More about : pci express royalcrown August 1, 2008 9:22:12 AM No Nytz, pci express is backwards compatible, you can run a 2.0 card in a 1.xx slot, or a 1.xx card in a 2.0 slot without problems. 1x16 has the same bandwidth as 2x8, and 2x18 has twice what 1x16 has and you can run any card in any of those, exen in a pcie 1x8 although it would be a bottleneck to your card. http://en.wikipedia.org/wiki/PCIe nytz August 1, 2008 9:28:31 AM Ok, thank you alot Can't find your answer ?
