Solved the issue. Windows update was the culprit.
Here is the fix for anyone that stumbles across this thread with the same issue:
1) Install whichever driver you want to use
2) Follow instructions described in answer here: http://superuser.com/questions/665158/can-i-prevent-a-d...
3) Follow instructions here (your looking for the name of the driver you want to delete such as: oem#.inf) :https://technet.microsoft.com/en-us/library/cc730875.as...
Essentially the first fix stops windows update from downloading drivers and the second is to delete drivers it already has so it cannot install them.
I am using the latest beta driver 15.6 fine on my box
what build are you using, 10162 is now available
