Upgraded to these as one of my games just wasn't working with 347.09,a first time for me.Wife and me play a game called Wizard 101 and her Intel HD3000 worked alright while i got the white flickering screen on load.Works fine now.
Not sure if it was driver related but my power settings after long periods of idle would readjust itself and every 20 minutes my screen went off.Going to 347.52 the issue has disappeared.
