8000 was as far as the graph went up and was there just to keep us guessing at the final performance. I think we can tell from the specs flying around that its gonna be in the ball park off 30% faster than a 7970ghz if the clocks are similar.
I hope you are right. If I was selling though, I would promote the speed as key if it was big and AMD did say they wasn't targeting the £999 GPU, so maybe that is the score.
Time will tell and not long to wait.
