<p>I would install some extra RAM in the laptop ( probably cheaper to buy it separately and install it yourself). You could go to 8 for an extra $50 (or less). Also you will need a good Graphic’s card if you are running solid works or other graphics and want to run it well. Some laptops can be upgraded easily others no. So check the software requirements well. You do not need to buy all the bells and whistles, just the ones you need. Once you know check the Dell website and see how much it will be to add only what you need.</p>
