its coming up to christmas soon and i was thinking on getting a new gaming graphocs card|||x box|||You don't choose different drivers, for games. You use the driver for the graphics card.|||Idiotic answers like Xbox 360 should be ignored and burned...Now, for these type of game you might only need a Geforce GTX 550, Not even that, but this'll run them quite well, since revalations is the newer Assassins creed, then you might wanna get 560 For that high Ultra mega chuck norris FPS (Frames Per Second).



Then you can get 550-570.
