This is a really nice site... one thing that could set your site apart from whattomine and coinwarz is to have a miner selection in addition to card selection..
as there are many miners and they always change.. if one could pick for example

RX470 + Claymore V11 for ZCash and get results

and then pick RX470 + Optiminer and get results

your site would kick fucking ass and put the others to shame!!!
