Being an old timer this graph is very interesting. At the start you can see how the brave new world of nvidia FX got slammed by a simple ATI 9700 card that just pushed pixels and did not push the envelope. Nvidia took that on the chin, the FX 5800 Ultra being the laughing stock of the entire world and got Dyson where he is today...
nVidia came back well with 6800 series, to at least get back into the ball park. It took them till the mighty 8800GTX, one of the best nvidia video cards of all time, to start the trend to what we have today. (As an aside, for the enthusiast the 4200ti is the best video card of all time bang per buck,if you are too young to have missed it blame your parents ball bag and vagina).
And being an old timer of 50+ years I do hope ATi, sorry AMD, pull off another 9700 with the latest card which is fast and cheap and sells loads. And makes the red and green tribes sling arrows at each other as it has always been.
Amen.
What about the blue tribe who will shoot at?
