With laptop mother boards each one is made specifically by the OEM for that laptop. It's very different from a desktop
The Vaio series seems to be all pretty rock solid. My brother has one that is at least eight years old, which just started to have problems (the screen died on it), but he is still able to use it on a daily basis. The only problem with that is, when people do have problems, it's hard to find parts. If it were a HP, parts would be easy to come by.
Your still able to use the Intel graphics, so unless you use it for playing newer games, I'd continue to use that laptop until it absolutely had to be replaced.
