The GT70 is a very good gaming laptop with good performance, very good thermals , very good matte 1080p screen and a good build quality. Read review.
Although the GTX 670M is not as fast as other GPUs you can get for this price, this specific GT70-0NC includes a 128GB SSD and a windows OS included and the Bigfoot Killer network LAN adapter. Also, it comes with 12GB DDR3 memory which although not very helpful for most games, still a nice addition.
Overall, if you like this laptop and the 128GB SSD and you are ok with not-the-best GPU (but a fast one) – it is a very good choice.
