Thanks for sharing
It seems that it still worth to use dedicated PhysX card even along with GTX 680
(Mafia II, however, is not a typical case - it benefits from dedicated GPU much more due to its.. particularity
Thanks:Good read there on Mafia 2
Alot of people are saying you do not need a Physx card with 680,but I think adding 450+ for dedicated physx card can make a game more enjoyable with the 680 GTX.
Now I am still waiting on another 680 to arrive and then I will see if Batman AC is even more playable with 680+680 for Physx.
SLI does not work too great in this game.
