It seems clear that a PCI-E 2.0 x4 (2000 MB/s) will handle a 10G 1 port card (1250 MB/s) but I'm curious what would happen with a 2 port card (2500 MB/s).
1) Would I be able to hit 10G on each port individually (assuming the other port is not busy at the same time)? Or does the card detect the PCI-E bandwidth limitation and cap one or both ports?
2) Also keeping in mind that the PCI-E speed is 2000 MB/s in each direction, does that mean that I could theoretically have one port sending at 10G at the same time the other one is receiving at 10G?
