Having said the above, the Sims 2 is a pretty old game. It was released back in 2004 therefore any Intel Core i5 CPU will have a graphics core that is able to play that game. However, the Sims 3 (2009) will not be as easy to run if you plan to play that game, then it would be a good idea to have a Haswell generation Core i5 CPU with the Intel HD 4600 graphics core, or any Core i5 CPU with a decent enough graphics chip. The Sims 4 will naturally be more demanding than the Sims 3.
