As pointed out by MrGaribaldi at the forums, earlier this morning Digit-Life website posted some technical specs and general information on the upcoming GeForce 6800 GPU family which is set to see the light any day now. Unfortunately the original article was taken down but here's a mirror for your enjoyment.
Although no performance figures have been unveiled yet, specs give a good hint the card will have power to spare... but then again if we should have learned something over the last decade, let's wait and see the real thing running real apps, then judge what is good for.
