I want to buy a laptop but I have a limited budget. I will install Ubuntu on it, and I use it for transcoding purposes, such as video editing, blender, audio-video conversion, so I need a CPU with higher single core performance. Many people complains of AMD CPUs for their weaker performance. I am not a game fan except chess but I also want a decent GPU.
Intel i5 5287u and i5 5257u CPUs has iris 6100 GPUs on CPU chip so they don't have external GPU. I tried to compare iris 6100 vs nvidia 920m but some say iris 6100 is only par with nvidia 840m, however it appears that in the following links iris 6100 is slightly better than even
nvidia gt 920m.

I am also interested in bitcoin mining. Considering all of these which one would you recommend? You can also suggest your own models.
bitcoin mining score for GeForce 920M is 39.92 mHash/s
bitcoin mining score for Core i5 5257U is 54.21 mHash/s
Single core performance for i5 5287U outgoes even many intel i7 processors.
