I plan on using my laptop (for when I travel and stuff), but this is not my primary computer. The laptop is alright, and I'm happy with it. I meet the minimum requirements however I don't know how well The Sims 2 will perform on Intel HD 4000 Graphics. I've been told Intel HD 4000 Graphics aren't bad, but it's still integrated graphics (I think) after all. Upgrading is not an option.

I think my laptop shouldn't have too much of an issue, but I am concerned about cooling.

We see a lot of people who have problems with that chip. Be sure to read and follow the suggestions in this FAQ:
