The Lenovo Legion Y520 is a fantastic computer. Lenovo does a great job of packaging in enough software to make users appreciate the ease of their system without adding bloatware. All the additional software aids users to configure thier systems to best meet their needs... As an i5 I was interested to see how it would stack up against my i7 Alienware laptop and my i7 Lenovo Ideacenter. I can boast that the Legion Y520 went toe to toe against what I would have guessed to be superior computers and was only off by the slightest of margins The alienware clocked in at 107 fps while the Lenovo legion got a 106 fps. (The ThinkCenter came in at 104.83 fps). The look and feel of this laptop is sleek and stylish. The performance is outstanding.
