Look at https://www.whattomine.com and if your card is listed there it should be able to assist you with an idea what your card can mine.  The information is out there which you can find through whattomine or through a search of google or this website. For future reference to help you get a better answer in this forum provide as much detail as you can.  What GPU, OS, CPU, PSU and RAM you are using.  The more information you provide the better an answer you will usually receive on the forum.  As always I would recommend whatever information you do receive make sure to do some of your own research especially when it comes to hashrates on cards.  With all the different brands and type there are many different ways to OC your cards to find what works best for you and your setting.
