The latest rumor says Polaris 10 with 980ti performance for 299USD.
Which of course is not true, AMD and or Nivida never reveals their pricing to AIB partners with so much time in advance. They do one or 2 wks maximum. (believe me, I know).
Besides it would reveal their pricing to nvidia, who would want that?
It's true that AMD is more focused on value, perf. per w, so I don't expect hiper performance from their Polaris but I do expect good pricing, but not as low.
Now back to pascal, I think Nvidia is not holding back their guns and they will kick *** with performance, which ultimately is what it matters in the end of the day.
