Depends on the kind of performance you're after. :)
If you're just wanting something better than 10GbE at minimal cost,
these work fine under Linux:
~US$40 each, not counting postage
They're rebadged Mellanox MHGH28-XTC cards. Completely ok to be
flashed with standard Mellanox firmware.
For cables, I use these:
US$14 each, not counting postage
Note, I'm comfortable getting stuff off eBay where the seller
seems ok. So far, so good. ;)
If you do decide to use the above stuff, and later on want a switch,
try and find a Voltaire ISR 9024D-M. They're DDR infiniband (20Gb/s
per port), and can run fanless (completely silent).
They can be had pretty cheaply if you're willing to wait for good
pricing. I got mine for ~US$270.
Hope that helps. :)
