Please Help Me Decide on a New Laptop!

[vansnav]

Hi, I'm currently looking into replacing my old laptop. Here are some of my specifics:

I'm a college student so I need it to do school work/videos/general stuff and be compact for the most part.
My budget is $700 or less.
I'm a casual gamer (DOTA2, WoW occasionally, etc.), so a dedicated graphics card would be nice but not required.
I want 6GB ram or more and at least a 500GB HD.
I would also like a decent battery life to last multiple classes without needing a charge.


I've found a few options which I'm considering:

-Dell Inspiron 15R Special Edition (http/www.dell.com/us/p/inspiron-15r-se-7520/pd) [It's got all the performance I'm looking for but it's bulky]

-Sony Vaio Fit 14E (https/store.sony.com/webapp/wcs/stores/servlet/SYCTOProcess?storeId=10151&catalogId=10551&langId=-1&orderItemId=157403755&mode=edit&LBomId=8198552921666564152) [Compact and sleek but poor battery life]

-Asus S56CA-DH51 (http/www.bestbuy.com/site/Asus+-+15.6%26%2334%3B+Laptop+-+6GB+Memory+-+750GB+Hard+Drive+%2B+24GB+Solid+State+Drive+-+Black/6904557.p?id=1218814071374&skuId=6904557#tab=overview [Numpad would be nice but no dedicated graphics card]

I'm open to any and all thoughts or suggestions. Thank you!

I think the Inspiron 15R will suits your needs - good discount, has an i5 which will get the job done and has a dedicated GPU.
