Hi I want to mine BTC with GPU (CUDA), 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? Would also prefer to cut out all the crap for the other coins to reduce compile time but was having trouble when deleting it from the makefile so I have kept it in for now.

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
