The NDA window was lifted today and so performance benchmarks for the Titan card are starting to show up.

More or less what I would expect based on the first info, it's the fastest single chip card, by a fair margin, but at a $1000 price point, it's topped by SLI cards costing $450 each, making it an odd item. If you can only use a single slot card for your gaming, or if you want to go way out there and run the Titan cards in SLI or 3xSLI configs, then maybe it makes sense. I think I'll be waiting to see what comes along in March/April. I expect the Kepler chipset refresh cards will be what I aim for since they are pushing their next full core advance, Maxwell, back into 2014. I expect that the Kepler refresh cards, with a modest OC will fair very well vs the GTX Titan at a much more palatable price point.
That being said, who wants in on some AMD 6970 super clocked cards???
