This is for a budget system for my sister. Staying as close to $500 as possible, mostly used for web surfing, music, etc. and the only game she will play is the Sims 2. The system will have a Sempron 2600+ on a S754 board with one stick of 512mb. This was the 6200TC I had in mind. I assume this would be enough to play the Sims 2 smoothly?
