I think that most of the people who are saying get the more expensive one are just the people who think you always have to have the best of the best. In your case, there is no need to spend the extra money on the higher end unit. You will most likely never use the dedicated card, and the slight increase in CPU isn't going to make a difference. If you were going to school for graphic design, or web design, video editing, etc. It would make sense to have a dedicated GPU, but for a college student, $250 can go towards a lot of other good things.
