Re: No GTX680 until Q2 2012
The thing is, that NV really wanted to price this card at $300, but they overestimated the yields, so they had to bump the price a bit. It is a mainstream chip after all and the only reason to name it like a high-end is because of AMD.
Just imagine, if AMD jumped in performance like it usually happens over one generation. Then GK104 would be called GTX 660 and they would have to be priced around $300-350 anyway.
If some of the rumors I'm hearing about a GK110 launching only after a month from GK104, then it makes perfect sense.
