Hi,
I'm currently using Claymore to mine Electroneum.
If you're on Windowds you could try the
BBT Multiminer. This is a video on how to use it. Dont forget to change your wallet details before you start mining though.
I'm sure there are other mining utilities out there, but I found this one the easiest to get started with. It is just a wrapper around several different miners.
With the AMD cards CryptoNight seems to be a popular choice to mine (Monero, Electroneum etc). Although it is also capable of mining other coins like Etherium/SiaCoin/Decredation etc.
Hope this helps you get started
