Crunching really large amounts of numbers has always been useful. And that's all this really is. Running weather simulations, Advanced math problems, Complicated engineering simulations. The space of possible uses is incredibly wide.
The last few generations of GPU architectures have been increasingly optimized for massive throughput of low-precision integer arithmetic operations, though, which are not useful for any of those other applications.
