I am not sure I can post it here or not. I just buy a new screen with higher resolution. But I find that my frame rate drops from 60 to 20. My original resolution is 1440 x 900, and the new resolution is 1920 x 1080. And I use the NV GTX460. I don't want to use the windows mode to player the game, and I want my frame rate per second above 50. What is the lowest graphics card for me? GTX 760? 950? 960?
