What is the best laptop available on Dells website right now? I have a 17% off promo code that can stack along with any of the promo codes that Dell gives. I am looking for something really fast that I can run programs on continuously. I am looking to use Nike.com Bots if that makes a difference. I am going to be using it for school work as well. Would an i7 be too much; should I settle for an i5? Thanks for the info
