For budget good hardware in a laptop, the Inspiron i7559 with the i7 6700HQ & 960M is easily your best bet. I would check Amazon over the Dell website, you can get them there for ~$800 new.
On the other hand you could save up/increase your budget and look into the new 1060 models that are being released at the moment. Supposedly performing within 10% of desktop cards. Any of the 10x series would last you much longer compared to a 960, depending on the games you plan on playing. Starting prices for 10x laptops is like $1500 US, so unless you only want one computer for home/on the go I'd stick with a desktop.
Laptop hardware is getting a lot better, it just comes at less efficient pricing compared to a desktop equivalent. You could probably build a desktop with the same hardware as that laptop and have money left over for something else that's portable, like a tablet or w/e.
The Lenovo y700 is also a good choice, they basically have the same hardware. I personally like the look of the Dell more + the keyboard layout, but the choice is down to aesthetics.
