I think the better way to phrase this would be to say 5870-level compute performance. I doubt we'll that level of graphics performance in this time frame for memory bandwidth reasons (unless we see large eDRAM/more relevant embedded memory tech). That said, if start having this level of compute power in most every new system being sold, I think we'll finally see that GPGPU revolution we've been hoping for for years. Yes, I realize it isn't a magical cure-all and that we would need a paradigm shift in the algorithms used, but the benefits are just right there screaming "Hey look at me, I'm a massively parallel computing monster that can be very good at the tasks the rest of the system struggles with".
