Now see how many gamers are using RX 480. Mostly RX 480 is bought by minners.
How does someone respond to a post as stupid as this?
Steam isn't market share and it has never given any clear indication of the number of cards sold.
And what difference does it make what the person uses the card for? I remember people on the AMD side of things saying the same things about the original Titan. If they are using it for gaming, compute, mining or as fancy doorstop, it doesn't matter. A sale is a sale and it's the amount of cards sold that decides market share not what people use them for.
