asus 1060 3gb dual  Mine are running for months with 60% TDP,  +100 clock, +380 mem  (it is Hynix)
fan is at 50% and temp are around 50-51C which is good for me.

It can probably do a bit more but I like to play safe +my electricity is costly.

p.s. this card is crap on ETH (and crap as a whole for mining but that`s another story) so don't even try it on ETH.  
Go for equihash and other algos.
