The Executioner Laptop from KillerNoteBooks has been reviewed by Tom's Hardware here and by TechWare labs here. It is quite a bit cheaper than the Alienware laptops and has the Core 2 Duo too. Only thing is, it doesn't have dual video cards. But it still is a very powerful gaming laptop. If you do want dual video cards, try the Assassin-X2. Fully decked out, it still works out cheaper than the Alienware Aurora mALX with the same specifications.
