Out of curiosity, would you buy a new computer just to play The Sims?

Depends what I was spending on the build, but probably not. You certainly won't see all the benefits of building a state-of-the-art gaming PC if you restrict yourself to TS4 since the optimization is so bad. It's only when you play games like Wolfenstein 2: The New Collosus at a stable 120 FPS that you can appreciate a newly built rig.
