Would an alienware m15x be good for DJ'ing?

I plan on producing and remixing dubstep and performing live. I dont plan on spending too much money on getting a huge rig. I really just want a simple setup like skrillex (he really only uses a macbook pro and an m-audio trigger finger and some speakers with ableton live 8) but since I dont have the money to get a macbook, I was gonna use my alienware, an m-audio triggerfinger and some speakers. I'm willing to save up for anything else that i NEED (is absolutely necessary) as I am going to be new to this. I already have ableton live 8 on my alienware. Thanks guys! and please dont give me answers like "OMFG A PC FOR DJ'ING??? WTF DUDE BUY A MAC N000B" because I am only 14 and we simply dont have that kind of money.
