Did you just hint at overclocking a laptop?
Jesus christ, unless they changed the cooling system DRASTICALLY, there's no way that would work unless you like having an 80 degree system.
Also you arguing graphics cards in laptops, which are also nothing special. And for video editing, I know this concept may be hard for some of you, but the video card doesn't do a whole lot. Processor and ram are higher up on the food chain in this case. the i5's and i7's are good for video, and whenever AMD gets off their ass the 'Bulldozer' line will kill as well.
Lenovo (IBM) makes some of the better laptops on the stock windows computers. HP is bleh. Dell shouldn't be an option if you know the difference between RAM and Hard drive memory. Apple makes solid computers, the price just isn't friendly.
