In this video I test out eXTremals Open Source ZCash GPU Miner for Windows. This works with both Nvidia and AMD Graphics Cards, and works in Windows and Linux.
I use a 6 GPU rig with AMD Radeon Polaris rx470 4G and rx480 8G GPU's in this video, which give me a hashrate of 176-18 Sol/s per card, for approx 103 Sol/s total.
This is a good start for a GPU miner for ZCash, and we should see better miners released later this week when the ZCash Miner contest wraps up.
