I followed the instruction from above however my experience was not the same. I did not get an immediate download. My version does now say beta though. Anyhow a tip from another thread regarding 1070 drivers helped me a bunch a major flashing (like eye blinking) problem I was experiencing has disappeared. I have minor glistening in some areas of the display I am not sure if I get updated with the beta if that will go away.
Edit: I verified that I have the latest BETA version.
