The real price for 390 cards is around 250$. Don't look at the old amazon offers which are ridiculously high. However I warn you (and everyone planning to invest in new rigs) that most probably by the time of arriving of the cards, the profit will drop so much that the ROI will be impossible in near future. Look at the plummeting prices of ETH and ETC curently. The pressure on ZEC and XMR is too high now, so they will not hold the current price for long.

I agree with that. If you pay more than $0.12 per kWh, it is not profitable to mine the ZEC, let alone ROI.

So it's not worth buying 8 rigs?

Buying 8 rigs to mine just zec wouldn't be wise ATM
Now mining something else in the down time of zec wouldn't be bad
I pay .13kWh and I haven't had a month yet that I didn't profit from
Granted some months I did better than others
Someone that pays high for power like me just has to keep a closer eye on the market
