My parents are divorced and I switch houses every week so a laptop is nessessary
Yea, I agree. Also, if say I get the 620M and a year later I want to upgrade to the 920XM, could I?
not really... computer at both houses
Gaming laptops are for gaming when you go places other than your home. I personally travel a lot and my laptop is great when I'm away from my desktop.
The Asus one is extremely marginally worse, so you should get it in my opinion.
I would rather carry it back and forth than to buy two computers
