^^^ Fair enough Brain....what I would do now that you have a new Card is simply run 186.18 Driver (last known "best" Driver without issues)...use until you get more positive "feedback".....the only problem with this is you'll ALWAYS have negative feedback on every single Driver (Evga Forum)...just pay close attention to whose complaining.
Trust me.....even with all the publicity re: 190.xx Drivers have stuck to 186.18..on my Primary Rig anyhow....if it aint Borked...don't fix it ;)
Glad you're on the path to straightening out the problem!!
