Is this Laptop any good?

I have been laptop shopping and I found one that looks decent to me with the budget I have (600-800) but I don't know if it's good for what I'm looking for. I play some online shooters and mmo's but I will generally use it for college work, listening to music, streaming netflix etc etc. The things I like are a long battery life (I move around alot!) and the ram. I will be adding games etc later on but it's not going to me my primary gaming machine, I have a desktop for that so gamings not a huge priority but it would be nice if this was capable of playing some of them at least on low settings as I don't get much time to sit in front of my desktop. If there are better laptops out there for my price range and needs lemme know! I'm too lazy to do it on my own!
