Bought another 290x...the seller asked me, why there are so many people buying his card 
and i got it first....i am even tempted to get another 290x but i think i will not buy it because its reference design and it will be noisier than a dozen of dual fans or tri fan models.

That is very good choice of using the 290X. For the ZCash mining,
10% more core of the 290x than the 290 makes some difference.
it is almost as fast as 390's but its about 50$ cheaper.
