Fun fact: short of buying a 10gigE card, your best performance will  
probably be from a cheap desktop board with Intel's on-board GigE  
chip connected via the "CSA" bus.  It bypasses the PCI bus entirely  
and drops packets straight onto the north bridge; this gives it a  
surprisingly large performance boost.  Only Intel would make its  
cheapest board outperform its more expensive server-grade solutions. :-)

In general, Intel's GigE cards are pretty good, and they're under  
$50.  It's hard to justify buying anything cheaper when you care  
about performance and reliability.
