Gurm I am doing light office stuff. Any laptop is fine for me. I have gone through my laptop history and to date I have never had an eye strain trigger from a Radeon chip (my old Lenovo T60 is a Radeon Chip). I don't think it's a matter of "quality", but a particular way these Intel chips implement some video output that triggers the eye strain, and the Radeon devices seem not to do that,
And the number of laptops with JUST an nVidia chip are rapidly approaching zero.
I don't think NVidia makes a motherboard chipset, so that would not surprise me. AMD, however, does. It would cost them extra money to solder on an Intel graphics chip.
