I had the 2010 version of this model, with the same symptoms starting in mid 2011. I would get 5-8 crashes a day from the GPU being on the fritz.

Apple ended up replacing the mainboard in a free out-of-AppleCare repair. I never had the problem again and I used the machine regularly until about 2018.

In my case, it lasted one or two more years, and I only learned about the repair after they stopped offering it. By that time, the machine had already been replaced for other, unrelated reasons.
