780ti is about as powerful as a 970 so its not that impressive gfx card, but it sure was expensive when it was released
I don't know about you but nowadays I really don't think there is much graphical difference in games between max settings and at the lowest. Sure it would be nice to experience all things screwed up to the absolute max and still have a fluid experience, but we pc gamers are blessed with the option/freedom to choose what settings we want. so just take it down a notch and enjoy the game because it is almost as gorgeous as at max.

@ 58-90 fps online @ custom settings, car is ultra, effects are ultra, track high and some things I dont care about at med with ds2 @1920x1200 and sometimes 1920x1080p
blur effects and such distracting stuff off, blah
if only the game itself was as bug free as it looks and performs
