Over 10 petaflops of processing power. That is 10,510,000,000,000,000 floating operation points. The GTX 590 was specialy built for these operations and was maxed out at 2,400,000,000. This makes the RIKEN the equivalent to 4,379,167 GTX 590's. Of course this is nothing compared to the TITAN project which will exceed 20 petaflops.
So if OP has a few billion dolars lying around I'm shore he'd be more than happy to dosh out for the RIKEN or invest in the TITAN project.
In all seriousness just go with the 670. You honestly won't notice a difference.
