Cheap, good ethernet cards?

[JParker at coinstar.com]

G'Day !

Your Beowulf project page mentions you used Kingston Technology products 
for your cluster. Brahma.  A quick serch shows that thay are priced about 
right.  Would you not recommend them on your new cluster ?

cheers,

Sailboat racing is not a matter of life and death ....  It is far more 
important than that !!!

This matches my own experiences, although I would have rated old-style
tulips as good as well.  I'd settle for a tulip-based card in the right
price range at this point, as you've put your finger dead on my fixed
budget choice -- cheaper card or downgrade from 1.33 GHz to 1.2 or
accept a slower FSB.  Or monkey around with diskless/diskful
configurations and so forth, which would likely work fine but takes more
of my time and work.  The problem is that this is about a 10% clock
improvement and my applications are mostly CPU bound -- I really want to
avoid an RTL card, but the 3c905 won't win much for me relative to that
extra clock on a 266 FSB motherboard.
