Doom 3 is a very good game. I know you dont need me to say that. After years in development under the careful supervision of the great man, JC himself, the final product has met my expectations. It also vindicates my decision to get new hardware in time for the time. The game makes full use of the latest features that the new line of video hardware has to offer and turns out a performance worthy of applause. It is no rocket science to see how this one game has influenced the video card battles this time around. The game is a run and gun FPS set in the most spectacular Mars space station ever seen. With great lighting and shadow effects it makes you feel like playing through a horror movie. Sound effects are truly awesome making full use of 5.1 surround. This game surely favors the Nvidia brand of cards as I experienced random crashes with my X00 Pro. So if you are in the market for new hardware for this game get The 6800 GT or ultra, they are the best.
