Alteon-based boards.  This includes Alteon ACEnics, the 3Com 3c985B (which
has 1MB SRAM), and the Netgear GA620 (which has 512K SRAM).

You can get the Netgear board for about $320, and the copper version of the
board for about $310 from www.necxdirect.com.  The 3Com board is about $680
from the same place.  (You're paying for the extra memory, which can make a
difference, albeit not an enormous difference.  Also, the Windows drivers
for the Netgear boards don't do jumbo frames.  I'm not sure whether the
3Com Windows drivers do jumbo frames, but I would guess that they do.)

If you want bandwidth numbers, see:
