Hi, I have Gainward GTX 560 1G5 right now but i want to buy a GTX680... And I also dont want to let GTX560 lying around so my question sounds: Is it good idea to use GTX560 (of course in PCI-E x16) as dedicated PhysX card for GTX680 ? And how many FPS can it add in Mafia II ? Thanks and sorry for my english
