You probably won't be able to put the settings that high on your integrated GPU, and a GT 630 won't be any better. The Sims will be perfectly playable, but not as pretty as it can get, and other PC games will have the same issues, but may drop below what would be defined as enjoyable.
Your best bang/buck option would probably be a GTX 750 Ti if you can afford it, and that'll handle Dolphin at high IR levels, and most modern PC games pretty well, but there'd be lots you couldn't max out, and it would be a shame to have such a fine processor paired with a midrange GPU, so if you're willing to put the extra money in for something better, it might be a better idea.
