It was said that it wont' be good enough for people to switch. But they will still sell many to people that say have a gf3 ti someting and want a better card, for those people maybe the 9700 wasn't enough of an upgrade to warrant the cost. But the NV30 might be enough of an upgrade to get them to buy.
Good point sngx. They said "only" a 25-50% performance increase between the nv70 and the radeon 9700. To me, that is a very big increase in speed. Basically that is like a new intel processor coming out at the speed of 4.5 ghz... wouldn't that be worth the upgrade?
Anyways... I am also one of those people with a gf3 ti200... but would probably upgrade to a gf4 ti4200 or something, because prices would drop and the cards would be still incredible.
