I'm looking to replace my old laptop with a gaming PC. Since I have found that building it myself would get me the most bang for my buck that's what I have elected to do. I have a budget of $500-$750 to spend and I'd like to get the best graphics that I can get for the price. I'd also like to be able to run Oblivion, New Vegas, and Fallout 3 as high as I can so keep those in mind when recommending parts. Also I'd like it to be able to hook up to a monitor via an HDMI cable. Include price of everything except a mouse, keyboard, or monitor.
