Do the math, if a x16 lane gpu generates 300 mh/s ( based off an average mining gpu), a sound card whether on-board or plugging into a pci, pci-e x1 lane, or even pci-e x4 lane is not going to do f*ck all, excuse my language. Sound cards are probably 1/100th the times as powerful as a gpu respectively considering release dates/drivers.

I have worked with computers for many, many years and I will confirm that this is false. This is just an outrageous claim.
