Since the rx580's came out, I have been using the mixed driver trick to get my rigs running on 7+ gpus of miscellaneous 470/480/570/580 cards in Windows 10.  With the newer released official drivers, do I still need to do this?

Also, regarding the beta blockchain driver, is AMD really done developing this driver?  I have seen mixed messages on that.  I got a nice bump on them but cant control voltages and cant control overclocks in Claymore.

thanks!
