Samsung - Laptop / Intel® Pentium® Processor / 15.6" Display / 4GB Memory / 320GB Hard Drive - Black/Silver - NP-RV510-A03US
This is $349.99. It meets the graphics card requirement (Intel Integrated Chipset, GMA 3-Series or above) with Intel® Graphics Media Accelerator 4500M.
It also meets the processor speed and RAM requirements. The graphics card one is really the tricky one to find on a laptop.
Please know that this does not have a 3d graphics card. All the laptops with 3D graphics cards that i saw were $1500+
That being said. She doesn't need a 3d graphics card to play the game, and she will be able to run it reasonably well (according to the specified system requirements) with the laptop above.
I'm an avid gamer and I've seen 3d graphics on PC's. The ones Ive seen were really not all that impressive... and they make me nauseous. :P
