To be completely honest, I personally would go with the 770 Lightning from MSI.
I have the 680 Lightning, and those cards are incredibly well made, and *fast*
They also have great overclocking headroom if you want to push them a little more, and they run very cool.
Only downside is that the cards are large. Make sure you have a case that can support them.
Compare to the ZOTAC AMP, is it better?. LOL Case is HAF X, im quite sure, it is more than enough. Unless i am mistaken haha
As far as build quality, noise levels, cooling and overclock potential, absolutely it is better than the Zotac. In regards to factory clocks it is identical.
The only downside to it is that it is still a 2GB card.
