Well considering I have the exact same laptop that Sherri is looking at I think I know what I am talking about. Why would I lie CTSluder? You think I am just making this up? Maybe there is something else going on with your daughters laptop that makes it lag. While we are talking about RAM I also only have 1 GIG of RAM in my desktop computer running Windows Vista Ultimate. No lag. Runs like a ROCK and that IS my Video game machine..,.
