This has been asked many times. It depends on what you are planning to use SW for. If you are designing complex parts orcurvy shapes with surfaces or a lot of rendering, simulation, large assemblies - you should follow the SW recommendations for a Workstation-grade computer. There are good prices found on the Dell small/mid-size office outlet. Look for a Dell Precision. There is also an outlet site for HP.
Many people get by ok using a gaming laptop. The problem is that if you pay for that and it doesn't work for your needs, then you are still going to have to buy what would have been smart to start with.
Do try Craigs List first. I got My current Laptop by searching for graphics cards on Craig's list. Dell M6400 Workstation 3 years old at the time for $300. The price of computers craters after they are sold. Take advantage of that.
If you plan on using a laptop for Solidworks, then you NEED a high end machine with a Quadra video card. One such computer can be obtained from MSI but you are looking at about $3000. Just remember when it comes to computers and Solidworks - you really do get what you pay for..... Solidworks is very power hungry and an absolute pig for video processing abiity. If you buy a cheap computer, then remember you have been warned.....
I'm sure it's fine.. btw,.. if you need RealView,.. do a forum search on "realview hack" and/or the web "solidworks realview nvidia workaround hack"
As Jeff said, it may depend upon your intended use of the program. I am an Industrial Designer and mostly work on plastic injection molded parts and assemblies, as well as cast and formed aluminum parts for the housewares industry. The files I work on are pretty complex but I have had zero issues using my laptops. However, I don't do any renderings or engineering tests on my laptops.
I used SolidWorks 2012 & 2013 on the Windows side of my 2010, 13" MacBook Pro until two years ago. The MacBook worked perfectly but I got sick of switching between the OS and Windows sides of the MacBook. So now I have an inexpensive ASUS laptop, that I bought two years ago at BestBuy for $700, running both SolidWorks 2014 AND 2015. I still have zero issues and no lag on this ASUS.
I run presentation renderings through KeyShot on our Geomagic Freeform stations, so I don't know if the ASUS will do renderings in a usable amount of time. So, as stated above by other users, if you need to do heavy renderings or engineering tests, you may need a high end desktop station with extra graphics cards and such. Good luck and congrats on going back to school. What are you studying?
Gaming graphics is not CAD graphics. Getting as gaming computer is not as good a hack as it may seem.
