May I ask why you need it to be on a laptop? If you're just modeling solids, then you might be able to get a less expensive laptop. On the other hand, if you're doing FEA and Flow, most laptops will have a hard time, desktops, even.
Also, I would recommend you run an older version of SolidWorks, as 2013 is still very new, and will be prone to bugs and kinks. The best versions are the free student versions, as they get released after SP 3 or 4, though their main downside is that they have the watermark.
Apoc, SW is demanding because of flow simulation and FEA software (SW is meant to cover everything from CAD to CAM), but depending on the version you have, requirements will be different.
