I am about to embark on my first ever gaming pc build. I want something that can run most games at high to ultra settings with 60 fps. I want a case that had room for upgradability and a windowed side. I would also like to keep this under 800$ if possible, not including Windows 8, or peripherals such as keyboard and mouse. Thanks for any help and If it isn't possible to build a pc for that price that runs games at those settings please tell me I can be flexible with the price.
