Motherboard: K9A2 Platinum. Running four video cards which means a quad x8 link. If I toss in a PCI Express x1 NIC, any idea what happens to my quad x8 link? Does it run x8/x8/x8/x4 +x1 NIC or what? Sorry if this is a real stupid question. I have a flexible PCI Express x1 extender, and would rather get a PCI Express x1 NIC over a PCI NIC for the extra bandwidth available, but if it's going to destroy one of the video cards' performance, I'll have to go PCI with a flexible PCI extender.
