studio xps is gone but new 2011 xps 17 is much more bang for your buck and much more professional looking.
yes, alienware is owned by dell
Desktop- Dell Studio Laptop- Dell XPS
I would recommend the Dell Alienware's
1. Asus G series or VX series 2. Dell Alienware
Dell Alienware
The alienware logo represents Dell Alienware gaming laptop. Though you can ask for alienware at your local gaming retailers or google retailers of alienware and it may have a separate site from Dell as well.
The type of brands that I recommend is Dell, Alienware (Made by dell), or HP.
Actually it always depends on price the features of a laptop, but I think that Alienware laptops are the fastest, and they are all suited for hardcore gaming. I would say that most of the Dell Inspiron models are only in the midclass in performance. To my knowing for 3000 bucks you can buy High-end Alienware laptop which will run anything you can throw a it. I will put an example link of an Alienware laptop, if you don't know how it looks.
It depends on what your old laptop/computer is and what the new Dell laptop is.
The best laptop for gamers is dell computers. Specifically, the best model for gamers is Dell Alienware. These computers have been featured on several gamer magazines. It has a long battery life and has very long lasting memory.
Dell Price $1799.00
I would suggest something from the dell studio series. Im not sure what your budget is but they have a dell studio to fit almost any budget.
