Firstly, I am a noob regarding to laptops. The Lenovo G50-70 59-443034 laptop comes with Intel Core i5-4258U processor. So can you confirm that it will surely have integrated Intel® Iris™ Graphics 5100? Also the laptop comes with AMD Radeon R5-M230. So will this laptop use the power of Intel Iris graphics+AMD graphics? Or only AMD graphics card?
Typically, the Iris graphics will be used for more basic tasks, while the Radeon would be engaged upon heavier use, e.g. Gaming.
