Pretty hilarious when I was searching around for SC2 and came across SC2 sets Nvidia cards on fire, though seeing as how most fires burn at least at 500 degrees celcius, guess they didn't quite mean it literrally. At any rate it's useful information for those of you who don't keep informed and are still running these drivers.
