i think NVIDIA have the best graphic cards that you can offer,but sometime,it turn to the onboard-->F*** THIS GRAPHIC CARD TYPE,and don't think laptops can't equip good graphic card!check the alienware m18x or m14x,those ar the best gaming laptop on the world!
I'm ganna guess you've never had a Falcon North West laptop like the DRX which Stock has better spec's minus the GTX 460m then the M18X, which can be replaced with a GTX 580m or 2 of them I'd prefer them any day over an Alienware
