The Nvidia 8-series in laptops is a known issue; Nvidia's had to pay out hundreds of millions of dollars. If it breaks again you should be able to get a replacement free of charge from the manufacturer even out of warranty.

It's called "bumpgate". It is a similar problem to RROD and totally not a normal failure you have to put up with.
