Hey everyone, i have an old emachines 2003 model with and amd athlon xp, its getting tied out. I have a basic knowledge of computers, and have installed memory, case fans, and a new power supply. I would like to build a computer to play some games on nothing high end, and mostly internet surfing. I am a big amd fan, and would like to build something for around 500 dollars. I usually order from new egg, so any suggestions.
