I'm a newcomer, definitely not a gamer but would like to build a really good quality, dependable, fast system without overspending. Would like to spend between $500 - $600. Already have a good monitor, mouse, keyboard, Office 2010 (32bit) & Windows 7 professional discs. Would like to go with a AMD Phenom II processor, on board video. I would use it for Internet, light office work at home etc. What would you suggest? Thanks in advance.
