Alienware vs Mac help me decide x.x?

That's tough, because I would definitely not pick a mac for gaming, but they would be the best for recording. So you would have to decide what is most important to you, games or recording. If you want to be more professional, go with the mac, because I'm sure that's what the industry uses. However, i'm sure as well that you can find decent PC software that will work probably as well. Good luck!
