Hi Gothic, thank you for this great post. But I still have some questions: 1) though the 3dmark score is helpful, it does not explicitly tell me % performance loss due to the laptop limited bandwidth. It would be great if you can give me a rough number. 2) Gtx 780 is a powerful video card, on the other hand i7 3720qm is weak compared to its quad core desktop counterpart. Would it be more suitable/bang for the buck to select a less powerful graphics card? If yes, which one? Thanks again.
