Hey guys I need a little help. For the past 10 years or so, I've been an avid console gamer, way before I was into computers. Currently, I have a PS3, Xbox 360, and Wii, so if I wanted a game, I would buy it for one of my three consoles. Meanwhile, my PC was used explicitly for Flight Simulators. However, since I have put so much money into my current computer, I wanted to begin to play some games on my PC. However, other than Crysis, I can't really think of any other games that will push my PC to its limits. I just wanted some input on some good, modern games (hopefully with a demo) that would allow me to get the most out of my PC. I guess I should also say that I already have all of the Call of Duty games (including MW2) on my consoles, and I am mostly into FPS games, but I am open to ideas. Thanks in advance.
