Hi I want to build a new pc and I have little experience. I want to get the most bang for buck price possible, so used is allowed (EBAY, CRAIGSLIST)! I live in San Jose, Ca, USA. It will be used for gaming, like Crysis and Battlefield, ultra, preferably 60 fps, with 1 monitor that's old (resolution is like 1280x720). No peripherals required, no operating system. Do you think it is possible, or will I have to stretch the budget?
