My current computer is taking a crap and I am thinking about building a new one myself. My budget would be around $500 AR but I don't need a monitor, keyboard, or a mouse. I have a dell studio 540 right now so I don't think I can salvage much if anything from that. The only games I'd play on the new computer would be the Total War series and Civ 5. Thanks for any help you guys can give me as I am a total noob when it comes to computers.
