Thanks to those giving advice rather than bashing on my question. Wow, I really did not catch how retarded my sentence structure was lol.
The reason why I compared a MBP 13" with the Alienware M15x is because of the price. They're roughly around $1500, but their specs are completely different. So I wanted to know where would my money serve me best.
Where I'm basically getting at is, if I'm going to spend $1500, I want one that will not drop in price drastically within the following year nor will it break on me within the next two years after the purchased date. I do play games, but not as much due to school...so the area of "gaming" in a laptop should be ruled out when giving the advice.
I hope this clears it up a bit.
