Well.. I only have NVIDIA GeForce Go 7400 (128 mb) and a friend of mine said I probally only have 1 gb of RAM or something.. but he didn't understood the diffrence between the sims 3 and sim city 3000, so I'm not sure..
The sims 2 runs smoothly on pretty good graphic options. My laptop is only 2 years old and it was the newest and best back then. I can't buy a new one yet
