Hello Ajay.

Like nid125 said, do NOT mine ADZ with GPU's, you will earn almost no ADZ and you will just lose money in the form of higher electricity bills. If you want to use your GPU to earn ADZcoins, it's better to use it to mine some other (ASIC-resistant) coin like Ethereum and then sell the ETH you earn for Bitcoins and then buy ADZ with those Bitcoins. That is how I'm using my GPU's. I'm mining ETH with 15 R9 Nano's (their combined total hashrate is about 399 MH/s) and they make me about 28 USD per day. My electricity cost is about 0.1 USD per KWh, so after electricity costs those GPU's make me about 20 USD profit per day at the moment. And with the current prices of eth/btc/adz that earns me around 465 ADZ per day.

I hope this gives you some idea on how to use (or not) your GPU to earn ADZ.

You didn't specify the exact model of the Radeon GPU you have, so I can't give you exact numbers. There is a web page somewhere that has ETH mining performance info on many different GPU's, but I could not at this time find it, but try googling it, it's out there somewhere
