Well he said he's got 3 1920x1200 monitors. So assuming he's gaming with eyefinity at 5760x1200, he would realistically need a minimum of 2 HD7970 level cards to have good frame rates in bf3.
So the choice is the eyefinity, the cards are simply what he needs to power such a set up.
(This is all assuming he is gaming in eyefinity of course)
