Yes, in the best of climates nv35 wouldn't do anything for nVidia until it ships (which is still a couple of months off at the earliest, I think.) But nVidia seems to have managed shooting itself in the foot--again--and has already put a damper on nv35 even before the first boards are shipped. In light of the pounding nVidia's taken in particular market segments because of the nv30 failure, anything like this is bound to have far-reaching reverberations.
Basically, the kind of people willing to shell out $500 for the nv35 reference-design cards that are being reviewed now (I note that only the most expensive version of an nv35 card is being pushed into the review circuit currently), are the very ones who know and care about things like deliberately cheating in benchmarks to create false performance impressions. As this news filters down into that market segment over the coming weeks it is likely that many in this market will change their minds about waiting on nv35 and go ahead and buy a less expensive R9800P or the equally expensive 256mb R9800P.
System OEMs will do things based on the number of orders they get from customers requesting certain peripherals, and this news is bound to diminish demand for these upcoming products and as this happens it will negatively affect OEM interest in the nv35 product line.
Thing is the current mess nVidia has gotten itself into is compounded with all of the current messes, and PR distortions and gaffes, that led the nVidia CEO to ultimately pronounce nv30 "a failure." It's not so much this one thing in isolation, it's pretty much everything nVidia's been producing, and saying, since August of last year. It's the sum total of all of this that's really going to hurt.
Hopefully nVidia will quickly learn that no amount of driver fudging and PR initiatives can turn a sou's ear into a silk purse...
What it needs to do is to produce a silk purse in the first place and the rest will fall into line. Let's hope they do better with nv40.
