yep same here,except havent tried any 1.6 boards yet.
not really trying to find an answer to the question of which
is better 1.0 vs 1.1 vs 1.6.im just trying to find the best
two boards to keep for my OCing fun
i will use the exact main components
like ram/psu/cpu/HD/cooling.i just need
to put in the tweaking time to get the
best results from each board.

so no i have 2xUD3R's 1x1.0 and 1x1.1
3xUD3P's 1x1.0 and 2x1.1's

i plan on keeping one UD3P and one UD3R
