I plan to buy a Sony Vaio as my daughter's first laptop. She liked one in store with Core i3, 500gb hardrive, & 256 mb dedicated video memory (2007 total), plus GForce 310m graphics. She mostly surfs and plays Sims 3. I'm considering a slightly cheapter version (both have 4GB memory!!) with 325 drive and 1726 video (no dedicated). Can this do the job? Its much more than I have now!
I assume the laptops you are looking at are going to run Windows 7? Check with the Sims 3 software in order to find out what the minimum system requirements. The Sims 3 is a graphics intense came so be sure that the laptop you select will be able to handle it,
Let me know if you have any other questions.
