Finding the laptop that's right for you is always a difficult task. All we can do is give you all the information we can on the laptop we have and you can apply it and hopefully make a decision based on that. I was in the same situation as you. My laptop choices first started out between Dell, Alienware and Gateway. For the models I was looking at: Dell (M140), Alienware (Sentia, m5500) and Gateway (I think NX550). I'm not saying there's anything wrong with those 3 companies but until I came to this website I did not know a thing about laptops. I then changed to looking at Sager (clevo) and Asus. From there it got incredibly hard. Both companies are very good quality. I then narrowed my choices down to: 5320, 3880 and z70va "refresh" Those are 3 awesome computers in my opinion. I read some reviews on the 5320 and as much as I wanted that, I just couldn't go with it. Then trying to decide from the 3880 and z70va I read countless reviews. I guess what really sold me was the screen on the 3880. The z70va has an amazing screen as well but I really wanted the 1920x1200 and I am very happy of my choice!
So my best advice to you is to live on these forums as much as you can until you decide what you want. There's a lot of information to be found to help you in your decision. And had I not found these forums I'd probably be getting an Alienware right now and still waiting to get it (phase game).
