Hello. I've found 2 laptops that i am confused about. One of them uses Richland Amd A10 5750m with Radeon HD 7970m dedicated gpu. The other uses Intel core i5 3230M with Nvidia gtx 675mx. I will be using it for gaming and studies. My question is that will the i5 laptop hold down the GPU? and also I live in an area with hot climate so I am afraid of overheating problems. Help me choose one plz.
