More about : pcie pcie DEY123 November 16, 2011 9:45:48 PM With that kind of a card I am pretty sure yes. PCIE1 is half the speed so it is like you are running PCIe2 on 4 lanes instead of 8 or 16. I think running on 8 lanes is probably even pushing it with a GTX590 Can't find your answer ? Ask ! Publish Related resources : ForumPCIe v2.0 x16 or PCIe v1.0 x16?
