Laptop for csgo 60~120 fps

Unknown.

There are no benchmarks for the Intel HD 520 graphics core yet. My guess is that you can get somewhere between 50 - 70 FPS @ 1366x768 resolution with low graphic settings. I recommend you save up money for a laptop that has a nVidia 940m in case you want to play games that are more demanding than CSGO. The 940m is not considered a "gaming GPU", but it is more powerful than Intel graphics.
