Hello, I recently purchased this laptop. These are the specs:

i5 4210M @ 2.60GHz
Radeon R7 M265 gpu
4GB Ram

I ran passmark and I got 1563 Rating, with 3754 points for cpu, 598 2d and 791 3d rating. I used my dedicated gpu for this.

I feel this is low and wonder why this would be, as the cpu for example has a lot better results in their benchmarks. I also have been getting lower fps than I expected. Or am I just expecting too much? How much would adding extra 4GB ram (dual slot) improve the laptop?
