Handy how? Seems like one of the most useless features to me, ~ same as LEDs. If you ever manage to flash a bad bios to your card (which shouldn't happen like ever if you know what you're doing), you can always boot with another gpu (any gpu will do, including the onboard intel graphics) and re-flash that card again. Dual bios is one of those gimmicks no one ever uses (buy pays extra for it). Sapphire Nitro cards are among the best though, that I totally agree with, but that's because of their good coolers.
