Is a great lappy. It's still gonna be heavy but atleast it isnt quite as large as a 17+ inch.
It indeed has a great vid card...not only that it's a bit more future proof vs the other...seeing down the road there might be more grphical games you'd want to play.
Asus is pretty top notch on thier support of thier products...while as Dell...well...you can browse the tech foums on the net and see what thier own employes say...*and it's not good...*
I've had a few dell gaming lappys and well...they tend to fall apart...driver support is stone age.
I think that is a great deal thou...maybe browse around and find it at a cheaper price if you can.* Thou I doubt youll find it cheaper*
By chance what OS are you planning on using?
Oh...btw with its rez being 1080p...you can always play games in uber glory...not only that...down the road you can always hook up a usb blue ray player to watch movies or w/e. So that option is always open.
