Yes, in a FPS, graphics is very important to me. I also don't go backwards and play outdated games. I don't play any game for more than a couple of months no mater how good it is, because I get sick of it.
Please, go ahead and name some games that I would be missing out on if from now on I avoid playing games that are based on the old unreal engine. I prefer games like Far Cry, Doom 3, and potentially Half Life 2.. T:V.. games that make use of the latest graphics cards. I also refuse to play the once great game, pac-man, but maybe that's hilarious too?
