Hi I want to mine BTC with GPU, does anyone recommend a miner not nicehash betterhash or those bloated ones I don't really want a big GUI just looking for something to connect with a pool on command line. I have been trying to get ccminer working but getting this error

GPU #0: result for 08742f4e does not validate on CPU!

Do people still use ccminer?

Is it hard to do your own what would you have to do send rpc commands to a stratum pool to receive the work and execute it on the gpu or something does anyone know of good documentation I was reading stratums but it wasn't explicit about using it for bitcoin. 

thanks if anyone has suggestions or material to read
