The gaming market consists of general gamers
and a small subset of those gamers are enthusiasts
have cards like the GTX 570, GTX 660s, GTX 670, 7950s, and 2GB 680s, etc.Enthusiasts
buy 4GB 680s, Classifieds, 690s, 7990s, Lightnings, etc..
Right now, Nvidia just released a highly expensive product that only a small percentage of enthusiasts
will afford, and it's been a year since Nvidia and AMD released cards that the average gamer will buy (680, 670, 7970, 7950).So we're due for a new set of releases, like the 700 series from Nvidia and the 8000 series from AMD.
Companies aren't (or shouldn't) sit on their asses when it's been a year since their last mainstream release. The mainstream market has a hole and it needs to be plugged. This is why Nvidia should released the 700 series and this is why AMD should release the 8000s series, and do it soon (ie, March/April like they usually do).
Despite what Nvidia says about Titan being a full production card, it's price tag will make it a very limited card, so they have to release something for the rest of gamers. This is where they release a ~$500 GTX 780. It makes no sense to me that Nvidia coasts an entire year off the Titan since most enthusiasts, let alone gamers, will never even touch the card.
Like Aparition just said:
Remove the casted aluminum... an[d] injection molded magnesium alloy, the plexiglass sunroof, the LED lights, give it only 3 GB memory, replace the 6 phase power circuitry with a 4, and gimp the GPGPU functionality like they did with the 6xx series.
Just give it a regular plastic shell with standard cooling and leave all the Gaming Graphic bits in.
I bet you that would knock off a good $400 right there.
This makes total sense. They can easily knock off $400-500 by doings things, and if they gimp compute features they can easily make the 780 perform close to if not better than the Titan. Then people might say that this kills sales of the Titan, but the Titan is in a market of it's own, since it does gaming very well and
compute very well. Someone who wants gaming AND
compute will buy the Titan and someone who wants just gaming will buy the 780.
