I still have my 2011 MBP with very similar upgrades, but unfortunately, it has the known bad Nvidia GPU that has been repaired multiple times. The last time it was taken in for repair, Apple said they were no longer supporting the repair. It's still usable as long as nothing tries to access the GPU, but as modern web tries to use GPU it would crash the laptop constantly.
Lucky you, so to speak. Back in the day I had the same one, but it would pass their diagnostics, so they wouldn't repair it, though I could literally make it crash in front of the Genius Bar techs reliably and repeatedly (essentially the same way, by trying to do anything that hit the GPU a certain way - websites, Photoshop). "Sorry, our diagnostic tool says it's not the GPU". At one point I even demanded they do a completely fresh install of the OS. On first login, I fire up Safari, go to a certain site, crash. Restart, go to a different site, crash. "Sorry."
I liked out in that mine never developed any issues with the GPU itself. Though it was stolen in 2014, so who knows longer term. My daughter is still running my (iirc 2014) model. I've been relatively happy with my 16gb M1 Air, aside from my own vision issues.
