Thanks alot in advance
Which has better display? I heard the lenovo has low frames per sec. Which messes up the display abit but thats older models right?

They are both around the same price.

The Lenovo y50 by a huge margin.

Looks like a gaming laptop from just looking at the specs. In specifications, it seems to be better in every way you can think of. The graphics card alone allows it to play quite a few of the newest games out there of today. Same with the CPU.
