That steam survey doesn't say a thing about selles, i never completed it, and my card isn't on that list. I bet many owners did the same as me, so using that chart as sourse of sales is ridiculous.
I bet that GTX590 will cost more, cause it's NV. It might be faster, but they won't be selling them as good as mid-end cards. This game of having "quickest" card on the planet is a bit silly, but it's like in sport, everyone wants to be the best.
I love when raven is defending his beloved company, anything that could put them in the 2nd position is nonsens
love it.
