Can my imac 27" handle Sims 3(MORE INFO in DESC.)?

DO NOT BUY THE SIMS 3!!! I made that mistake. Theres a huge glitch that the developers are well aware of that randomly deletes your Sims. It's been like this since October and still hasn't been fixed. Don't believe me? Go to the Sims 3 official forum and search "vanishing sims"
