I browsed a bit and, looks like, for that price you won't get a very good gaming laptop - video cards are pretty weak in these. Make it $1200 or so - and you can buy a very good gaming laptop, like this: http://www.bestbuy.com/site/acer-17-...=buyingOptions
Regardless of what laptop you end up buying, my recommendation would be to get a 17" 1920x1080 screen since they seem to offer the best performance/price relation and are comfortable to game on, and at least 560m/660m/760m graphics card. I know the games you indicated do not demand much from the graphical point of view, but any decent i7 processor is able to handle them well so no need to limit graphics for it, and 760m is, I think, exactly what you need to max almost all settings in Wildstar/WoW and still have good FPS (40+) in most cases.
The GTX 850M is a much better GPU than the 840m and it comes with a i7-4710MQ CPU as well. Thats about as good as your going to get for that price.
