most of the video cards used in mining are GDDR5, I found a very cheap EVGA 1080 GDDR5X card in a reliable store, and I'm suspicious that it is not a good card for mining, I'm thinking it's cheap because the memory is GDDR5X and I only see people using GDDR5 in mining

Is this video card good for mining?:

can I get 500~550 sol/s with this card?
I'm mining zcash.
