Sims 3 System Requirements: Maxed Out + Smoothly?

[-[gooey kablooey]-]

Hello fellow computer geeks!

My dad and I are thinking of building/buying a computer on which I'm going to play sims 3 and other games
since my laptop doesn't play it very well.

I was wondering if you could tell me based on the requirements what would play maxed out settings and play it
smoothly. I don't want to spend lots of money only to find that the game doesn't play at the best quality and speed.

I looked around on Google and such but I couldn't find anything. Any suggestions would be appreciated. {yes}
