Need to use PCI-X bus for 10 Gb ethernet.
66MHz*32 bits = 2.112 Gb. This is the absolute flat out MAX the PCI bus
can push.
PCI-X:
4.3 GB/s=34.4 Gb/s = x3 10 Gb ethernet cards = $3700-$4700 EACH!!
(<a rel="nofollow" href="http://www.small-tree.com/10Gb_order.htm";>http://www.small-tree.com/10Gb_order.htm</a>
and

{NOTE: The smalltree site has a 4 port Gigabit adapter for the PC that
is Linux supported :)}
The Peripheral Component Interface [PCI-X] addendum is an enhancement to
the current 64 bit 66MHz PCI bus specification. The minimum clock speed
for PCI-X is 66MHz [PCI-X 66]. Additional bus speeds include: PCI-X 133,
PCI-X 266 and PCI-X 533 providing up to 4.3GBps [PCI-X 1066 in the
works]
