What non-shooter game really tests a top line graphics card?

I am getting a Dell XPS 850 with a really hot graphics card and want to test it with a game, but am not good at the shooter or other quick reflex games. Do any use super good graphics and perhaps an interaction that will let me see what I have paid for? Otherwise I will use it to edit video and RAW pictures and that ought to be test enough. Still, I may find a game I really like.
