1056 is theoretical number. Normally you need to read from the card
and write to network adapter, so it is twice less. In practice it will
be around 400Mbs. 

I am streaming about 130 Mb/s from machines with 6 cards but they run
1.3 GHz Celeron processor which is then fully loaded. Tests would need 
to be done on 3 GHz Pentium 4 to see how much can be pumped then.
