I'm going to be buying my 15 yr. old daughter a new laptop. She will be using it to do her homework, social networking (Facebook, Twitter, Youtube), playing The Sims 3 and for downloading music and pics. I'm trying to decide between 2 that both cost $400.00 on sale. Any suggestions would be greatly appreciated! 
Lenovo Ideapad Z570 1024-3VU
2nd gen. Intel Core i3 processor w/ 4 way multi-tasking 2.1 GHz speed
4 GB Ram

Memory type DDR3 SDRAM
Integrated Intel HD 3000 graphics card
OR
Toshiba Satellite L755-S5256
2nd gen. Intel Core i3-2301M processor w/ 4way multi-tasking 2.1 GHz speed
4GB Ram
640 GB hard drive
memorty type DDR3 SDRAM
Intel HD graphics with 64MG-1969 MB shared memory graphics
They both are 15.6 LED screen and have Windows 7 Home Premium 64 bit installed. She already has a Toshiba Satellite L305 that has lasted well. I'm going to give that to her grandfather and upgrade her so she can play The Sims 3 on the new one. I'm just a little confused on which will be the best since from my little bit of knowledge, they both seem pretty much the same except for the graphics and hard drive storage. Thank you
