mushy101: I don't think it will work, at all. Playing a game below the minimum requirements could lead to all sorts of error messages, lock ups, false starts and artifacting in game. Then we get onto the problem of the frame rate. Expect 5-15 FPS with that card, even if you can manage to start the game up and play.
So yes the game MIGHT work, but expect to have a woeful, ugly, utterly poor experience within the game with your current GPU.
I am more then willing to help you decide a gpu upgrade, since that really is the only option to play TW2. What is your budget, if there is one?
I don´t really have a budget, but i am willing to pay as much as i have to, but have in mind that i live in uruguay so the latest video cards may not be avaivable.
