Lenovo Y510p SLI or Alienware 14?

I need a laptop that I can do school work on, but I would also like to start doing more PC gaming. I'm slightly torn between these two laptops. The lenovo is cheaper but I think the alienware is a better computer although i've heard it runs a bit hot at times. If you guys could give me any advice on which one to go for that would be great, or suggest a different laptop that would be good for what I would like to do with it. Also I would be looking at the mid level Alienware 14 with the 8GB of memory, not the 16GB, as my price limit is about $1400 or $1500.
