I've heard that the 3rd generation of mobile i7's are beasts.
I personally like ASUS' laptops as it seems to me that they create laptops with high specs and quality for less money. In my experience ASUS laptops are also VERY quiet (cooling) laptops.
For the graphics card performance, look here:

GTX vs GT: GTX are the higher end graphicscards, companies like Alienware and MSi usually use those GTX cards because they spend more on the cooling of their laptops. I don't think I've seen a GTX card in an ASUS yet.
You're saying you want this laptop for travels right? I'm not sure if 17.3" is the right choice here then. I have a 16.4" laptop, and I think it's a goddamn weight to carry it around.
