Republic of Gamers Asus G53SX
Compared to other 15" notebooks its had more bulk and weight (3.92 kg). And it's aggressive design practically screams 'gaming'.
@ 2,91 kg the HP dv6-6c50ez
is more both lighter and thinner plus being more restrained in appearance.
It's available options include: Core i7-2670QM CPU, 8GB RAM, 1TB HDD (upgrade to 7200rpm if possible), 15.6" 1920x1080 anti-glare LCD with Radeon HD 7690M XT
The 'best guess' for Guild Wars 2 system requirements that I could find where @ [url=http://www.guildwars2.com/en/faq/#thirteenhttp://www.guildwars2.com/en/faq/#thirteen"The system requirements haven't been finalized, but just as with the original Guild Wars series, we're committed to creating a beautiful game that will play great on mid-range gaming PCs."
The Radeon HD 7690M laptop graphics card is roughly equal with a Radeon HD 5670 desktop graphics card. My guess is the HP dv6 would run Guild Wars 2 well, but maybe not at maximum settings.
