You're mixing retail price with wholesale price. The $69 price is
apparently quantity 10,000, for just the chip, and the card that
is inexpensive will be PCIe 4X, which hurts performance.

I hear that today's street price for Mellanox-based cards is ~$600 in
cluster-sized quantities, which matches what you report.

One nice thing about Myricom is that their prices have always been on
the web -- all you need to know in addition is your discount.
