So far 5656 stable, but I've been somewhat conservative with the vcore.  Chip was advertised as a 5650 but I'm hoping to get on top of that ?
The two cards I'm running on air are EVGA SC (have one more, but it has a water block on it right now).  Have a nice MSI Lightning all waterproofed with heat sinks and a fat boy already to go.  Wife gets home early tomorrow so may not happen til the weekend.  Worse case, Monday depending on her agenda 
 
Have to setup my R4E too .... so little time, so much to do
