Since you just bought them, I assume you bought 3 of the same card.  And I 
also assume the old cards were whatever was laying around.  Unless you know 
how your motherboard numbers things, picking which is card one, and which is 
card two can be non-intuitive. :-)  Therefore, shut down, and swap all the 
cards.  Come up with a console (monitor and keyboard)  and autodetect LAN 
and WAN.  If your DMZ is still called OPT1, your can auto that.  If not, 
skip it.  Go into the LAN port and assign the DMZ to the card that is left. 

Note:  A backup config is always a good thing to have around...  Not just 
for changes.
