For the person looking for a laptop to play world of warcraft, if you are only going to play older games, wow is 7 years old. I run it on my Acer W500 tablet on low settings at 30fps... an amd quad core with a 6520g will play wow fine with high res low settings as in shadows, draw distance blah blah. All off or low.
If my 2gb dual core TABLET can play wow... the samsung laptop thats available here can play it at least twice the settings. My tablet is 1200x800 with low settings. And its a smooth experience on a 10" screen.
WOW is hugely outdated, so any system can play it. I have played it on intel hd 3000 graphics. Dont listen to people telling you that you need 800$+ systems for wow. Those will play newer games on medium settings.
With a 6520g you can play a lot of games on low settings and get 25-30fps. People dont know what they are talking about and expect that they need monster graphics cards that cost more than their systems, when in reality most developers make games that run on most any systems. Like Guild Wars 2 runs fine on intel hd 3000... which is a terrible graphics solution.
If you are okay with low settings any amd llano chip will let you play games fine, thanks to quad core and 6gb ram. 6520g is an impressive graphics solution. Just dont expect to play games that are blockbusters like battlefield 3 orMetro 2033.
If wow is all you want a 300-450$ laptop is more than enough. I promise you that... i also play torchlight, diablo 3, and other games have equivalent graphics, indie games like orcs must die, or limbo. So and quad core A6 amd and 6520g with 6gb will play wow, guild wars, diablo 3, and modern crapfare and even skyrim with lower res. Because the gaming industry is being held back by consoles and most developers try to "avoid piracy" (aka make it available to anybody with money) by making games playable on consoles then port them to pc for extra cash. It is rare that you see PC only optimized games anymore.
Next gen we might see better games... but right now there is no reason to buy more than you need. People with 680gtxs are kidding themselves... I have a 570 and max every game on my desktop easily. A high end gaming desktop can be built for 700$. Low end?? Easily 400$ its just a matter of what you will put up with.
