Benchmarking is more driver tuning than it's videocard performance, and if you want to look at number crunching you should look at the most recent gens.
The 680 has brought nVIDIA back up top for number crunching (forgetting the silver editions or gimmicks like the titan), and close enough to bang for buck best, but AMD's response to that still has to come. Ironically, though, the 6xx gen is reported as a crippled, bad performer in DCC apps, although I can't say I noticed it myself. It sure as hell works admirably well in mudbox, mari, cuda work, and I've had no issues in maya or soft. I don't really benchmrak or obsess over numbers much though. When this will obsolesce, I will considering AMD again, probably in a couple years. For GPU rendering though, well, that's something you CAN bench reliably with the engine, and AMD might still win the FLOP per dollar run there, so it's not to be discounted. Would be good to know what the redshift guys have to say about it themselves though if they can spare the thought and can actually disclose.
