i don't see why you insist on which path did nv30 use?
it prolly isn't ARB2, but i really don't care if r300 and nv30 use different paths if they can do their work. from standard point of view of any gamer out there there is no importance whatsoever about paths or anything.......they are only interested in HOW FAST does certain card perform (me included).
and if i remember correctlly JC said that nv30 is twice as fast as r300 when it uses it's path.so we will prolly see even better results when the game and nv30 hit the shelves.
do you honestly think that any reviewer and specially any highely hyped gamer will even bother to think about paths??.......they'll see results and as long as nv30 can produce results it will be good card.
