If you have a real computer store (Micro Center or Fry's come to mind) within a reasonable distance, you might be better off making an in-person visit and asking for guidance. I have limited experience with Fry's, but I've always found Micro Center's sales staff to be very customer-centric. I've sent many people there who walked out happy and remained happy with their purchases. Their salespeople may upsell (laptop cases and the like), but they tend not to oversell (sell you more machine than you need). At least that's been my experience.
