ATI R9700 was offically annoccued Aug 7 of this year. Comdex is not till Nov 18th (no word on which out of the 5 days that Comdex runs will they tell us about nV30). Which is closer to 3.5 months than it is to 2.5 months
Even though the card isn't released you are effectively saying the previous model is now out of date and requires a refresh.
Nope they can say that they are responding to the market (ie read this is our answer to the nV30). We all now from Anandtech that R9700 core can reach as fast as 400mhz. Slap on DD2 and then nV30 has little if any advatages left...
