AnandTech takes a look at what to expect from NVIDIA within the next couple of months, you can read it over here.
NVIDIA could get into a price war with AMD, but given that both companies make their chips at the same place, and NVIDIA’s costs are higher - it’s not a war that makes sense to fight.
NVIDIA told me two things. One, that they have shared with some OEMs that they will no longer be making GT200b based products. That’s the GTX 260 all the way up to the GTX 285. The EOL (end of life) notices went out recently and they request that the OEMs submit their allocation requests asap otherwise they risk not getting any cards.
The second was that despite the EOL notices, end users should be able to purchase GeForce GTX 260, 275 and 285 cards all the way up through February of next year.
