I am going to build a new computer for a long time family friend. He wants me to build his 15 year old son a gaming computer with a budget of $800-$1000. I am willing to drive around different stores like Frys and Microcenter but will probably do most of the shopping through Newegg. The new ATI 5770 seems like a good start. Please give me some ideas. Oh and I am not going to overclock. I want this computer to be completely stable.
