Hi to all. I recently obtained a Zotac 750Ti. I am already using 780TI SLI so I thought of using 750Ti as Physx Card. I tested two Games, Batman Arkham City and Mafia II, if 750Ti as a dedicated Physx card is better than a 780Ti. Here are the results.. Batman Arkham City: 780Ti SLI with 780Ti as Physx Average: 94 780Ti SLI with 750Ti as Physx Average: 106 Mafia II: 780Ti SLI with 780Ti as Physx Average: 59.1 Rank C 780Ti SLI with 750Ti as Physx Average: 108.1 Rank A I must Say...750Ti is a very good Dedicated Physx Card. My only concern is I have a problem testing ACIV Black Flag. I can't set Physx when 750Ti is set as Physx. Thanks for anyone who will be reading this Post.
