My original 759 was awesome, till a ram slot went dead.  RMA was smooth and fast.  Had to RMA the second 759 due to pure stupidity but still have my original 769. 
I've watered and frozen them both, and they continue to perform like champions.
My 762 will be delivered Monday morning (the 12th of April), and it's going straight into the deep freeze.
My P55 Classy is still in the box 

 but I'm itching to get it and the 670 frozen too sometime soon 
 
Work has kept me out of town and away from my boards too much as of late, but can't say enough for the Classified's I have owned, or for EVGA who makes them and stands behind them 
 
Kind of miss my RIIE (it was my first X58 board), but would never change back cause it didn't give me the versatility that the Classified's do.
Classified board sale coming sometime soon, only because.. who really needs 4 different models at one time 
 
 
Thing is... I don't want to give any of em up
