I have NVIDIA Quadro K420 graphics card and total available memory is 10204MB. But I am not sure whether I have GPU or not?
That's your GPU, but it isn't powerful enough for mining.
i Think NVIDIA Quadro K420 to low specification for mining. we need high specificatiaon.
but, if you ask to me, what the best tools for mining? i will answer :i dont know!!
.
I think we must make a colective reseach to find the best tools.
