I don't support Origin either, but it is better than Alienware. You only go these vendors if you know nothing about computers, you have a lot of money, or don't mind bad customer support or build quality.
If you do want to go to these companies, Origin>Alienware by a large margin.
Alienware not only slaps on over $500 than the regular retail worth, but it also has terrible build quality on occasion. Some people have reported DOA's, blown capacitors shortly after they get it, and their computers dying within a week of getting it, and customer support not being able to fix the problem.
Plus, their laptops are the worst. Their laptop line has sub-standard cooling, most people have seen that when playing certain games, their GPU temperatures exceed 85°C, which is too hot for your hardware and will drastically shorten its life, sometimes cause it to burn up or your OS to automatically shut down your computer as a defensive mechanism.
