Okay... As far as I'm concerned Alienwares are just Dells with a higher price tag. However I may be wrong. I know that my friend had bought a quite expensive gaming laptop that will run everything smoothly(Even Crysis at the time of purchase[Not sure if that is used as a benchmark anymore]). He bought the laptop from Vigor Gaming
. He said it costs about $3,000(a bit outrageous if you ask me) but it is a high quality computer and will last you quite a bit. What is your budget, and if I may ask, why a laptop? You can't really upgrade them as easily as a desktop. Incase you didn't catch the hyper-link then here is a direct link to the Vigor site. Vigor Gaming Computer - The Ultimate Gaming Computer for the Extreme PC Gamer
And here is a direct link to their Notebook section. Vigor Gaming Computer: The Gaming PC with Extreme Vigor™
And a little extra note: I have spent countless hours on his computer. The arm rest area/touch pad area gets hot occasionally when the computer is under full load, but the heat is bearable. The exact model he has is the Artorius Pro
customized to his likings.
Edit: Keep in mind that I know next to nothing about laptops and how they should preform under certain conditions.
