You have to test... I'd say one of the things you will run into is the number of interrupts coming at you with so many cards.
Personally I recommend one card per box. The card goes for $1800(I buy Sangoma with echo cancel) while the computer goes for $800 (HP Proliant 145). So the computer is really the small expense here and with one card per box I instead have several boxes and thus better redundancy. One card per box also guarantess I won't have any interrupt problems and it's capable of transcoding.
