I'm about to buy a new laptop computer. I might want a better NVidia GPU on my own computer in the future, and it would be great to keep that option open without buying an expensive machine right away.
I didn't find such information on any laptop available online, so I fear this generally does not exist, at least not for lower-cost models. This PCWorld article from 2015 suggests that it's possible for some laptops made by the manufacturer Clevo.
The question: Are there laptop computers in the range of 1000-1300€ (-1500 USD) that allow to upgrade the GPU? If not, what would be the minimum price for such a computer, if they exist?
