Honestly at around $800 the Y510p is your best bet because of the GPU and CPU. (I saw your other post earlier, you said 15" I believe)
I don't know where you got the idea that there are better options at the SAME price. (I really can't find any better options at $800)
For about $900, yes there is in fact better options.
BTW, which model of the Y510p are you referring to? If you're referring to the cheapest model, I can see how some people say that there are better options at that price(Because of the 1366.768 screen and the 5400 rpm hard drive). But those options most likely have a less superior GPU.
