Graphics are so/so, and use shared RAM (the same as the rest of your computer) so the laptop essentially has 384mb of RAM, which will lag you to death in Orgrimmar and most 40 man raids, depending on your mods, and what else you have running while playing.

If you don't need the nicest graphics, this would likely be ok if you upgraded to 1GB of RAM, and don't mind Windows Media Center edition
