Which miner (software) is most popular today?

Hello~ Everyone~

Could anyone give the advise for which miner (software) should I choose ?
For Windows X64 , supporting both AMD cards & NVIDIA cards.

Thanks!

For Nvidia, I use ZEC miner.
For AMD, you can use NiceHash

Any way to do mining if my rig contains 1 AMD card and 1 NVIDIA card ?

There are options in the miners to set supported devices (cuda/opencl) to mine on.
Just take a look at options in the docs for more info on this.
