I am in the market for a new laptop. The use of this laptop will primarily be for browsing and multimedia. I also prefer to run linux(k/ubuntu), but will be dual booting some flavor of Windows as well. The most resource heavy programs I use are Code Composer Studio and GIMP. I am not a gamer. Without giving too much info as I don't specifically need anything other than WiFi and BT4.0. Should I be looking at A8, A10, i3 or i5? By budget is $500. Specific suggestion?
