I'm looking to buy a new graphics card as my old one quit on me (GeForce 8800GTS). However, I have no idea what I should get. I'm not looking to get anything more expensive than $300, and I would like to be able to run my games at 1920 X 1200. I don't care with Nvidia vs. ATI, I just want to get the best graphics card for the money. I appreciate any recommendations.
