No problem. In the end it was _my fault_ for not reading carefully the
card specs. I made a bad assumption based on wrong information.

One of our company networks was installed from scratch on later 2005 and
I made it Gigabit (STP Cat.6) but should I have now to do it again I
would consider in adding 10 Gigabit capabilities, at least for the
cabling (devices are still overpriced): it costs just a bit more than
gigabit (it's affordable) and you can still use your old gigabit devices
(network cards, switches, routers...) but you're ready for the next level.
