Hello Merry. Welcome to the forums. :- )
I use to work at a large computer retail store and now at a company where I am the IT guy that handles all the laptops (and desktops) before they are distributed to everyone at work. From my experience Dell, Toshiba and HP are all good brands. Just like cars and other machines that are man-made some are lemons. So you will get a group of people that say Dells are horrible, Toshibas are crap, HPs are lemons, etc. I did some research for you and your daughter on the 3 best mainstream companies I know of (HP, Dell, Toshiba).
The following 3 laptops have similar configurations. All 3 are very good laptops for a college student and will play The Sims 3 smoothly (but at lower resolutions/graphic settings). Your daughter will be happy with either one but for $924 in my opinion the Dell is just too expensive.

$924 Dell -
http://bit.ly/Dell-lap-Studio15-070709While the 3 laptops above will run very well THIS YEAR, I recommend purchasing the higher-end Toshiba below. In 3 years from now it will still be a decent system while the 3 above may be considered “too slow”. The Toshiba has a faster CPU engine and an outstanding graphics card. Both of those specs are superior to the 3 laptops above. Also whenever The Sims 4 is released (which will probably need a faster laptop than Sims 3) this laptop will more than likely be compatible while the 3 above will not. Btw, I checked the HP and Dell sites for a similarly powered system and they are too expensive. You would be burning your money compared to this Toshiba model’s pricing.
