ibuypower machines are very bad - I've never heard a positive word about them. If you want help choosing a new notebook, go to the laptop section, open Maziar's sticky (right at the top) and fill that out in a new post. You'll get notebook config recommendations in no time.
And alienware is a good choice to stay away from, yes.
I recommend Sager notebooks - basically, they will offer you the same two notebooks you looked at (they're all from a company called Clevo - numerous companies sell them) - except Sager support is stellar and they use parts that stand up to time. A Sager machine will also likely be cheaper than that one you had there. You can also get Clevo machines from killernotebooks or xoticpc.
