HELP I want to build a PC, which I have never done before. I have a 600 dollar budget for the whole setup(Things like the OS, monitor, keyboard, mouse etc) I know it is small but I have hope. I don"t know if this is a good build or not. I don't need to run super demanding games but I would like to run higher end games. The lower the price the better, but I want to run games well so I don't mind going up a little (50 dollars maybe) here is what I have http://www.amazon.com/gp/registry/wishlist/35WLQL9BCUT21/ref=cm_wl_huc_title
