The Lenovo Y50 is an amazing gaming laptop, I got one for my brother as a gift and it's really impressive. I feel like it's priced a bit cheaper than some of the other options mentioned, but it's a good entry in the high-tier genre.
Just remember to play something a bit more intense than Graal  |
Yea Reece suggested a lenovo as well, and whilst they are very good computers, one of the things I'm looking for primarily is the 17-18 inch screen
