No problem. In the end it was _my fault_ for not reading carefully the card specs.

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.
