There are two laptops which I narrowed down. Both have roughly the same price, only the cpu and gpu are different. I usually watch some videos and do my assignments. I only play some 'light' games like csgo and paladins and I don't expect to play these on high settings at 60 fps. I'm fine with just playing on low as I only play casually. Which one would serve me better in the long run as I'm still just a college student.
Both the i3's are almost on par with each other maybe a slight increase in speed on the 6100. I would personally go the i3 5005u + GT 920m over the i3 6100m + Intel HD Graphics since it comes with a dedicated GPU (GT 920m). The GT 920m isn't necessarily a lot stronger than the integrated Intel GPU on the 6100 laptop but the fact that it has dedicated VRAM and would utilise Nvidia drivers for gaming i would go with this laptop. The GT 920m would also be better in workstation apps if you any CAD or Photo/Video Editing. Hope this helps
