DNA wroteactually i think reflowing is worth doing if done correctly cause the issue may be solved forever, anyway reballing is the better option and i do it for my customers for 50$ and if a gpu replacement is necessary i charge around 100$ or maybe more according to what GPU is in the laptop.
A new laptop starts from $285+VAT nowadays. Do you think anyone who needs a 5+YO GPU? On the desktop side, the original Intel HD graphics was slightly slower than the 9400GT (Very popular card). So, if they can live with such slow speeds, I don't see any reason to fix it. Unless it's CUDA or OpenGL, or they just want it to run temporarily and get a better upgrade later or something. I really don't recommend people to fix old stuff. They're keep having problems with other things in the future, and eventually pay for repairs more than a brand new laptop that would set them for for a few years already.
