A stock GTX670 is about 15% faster than a stock 7950. The 4 games have now been out for quite awhile and are selling for as low as $4 (Blood Dragon) to $10 for Tomb Raider and Crysis 3.
Problem is GTX670 went on sale for $330-350 many times in the summer of last year. Anyone who is excited about a $299 GTX760Ti was simply too broke to buy a GTX670 for $330-350 last summer or has no clue how to time GPU purchases. No doubt a $299 GTX760Ti with 670's performance is better value than HD7950 V2 for $280 but HD7950 V2 itself was going for $280-300
11 months ago.
Sometimes I wonder who in the world buys GPU refreshes. Most of the time they are a waste since they barely provide any improvements over original cards in terms of speed and the opportunity cost of waiting 12 months to get a card slightly cheaper / and or 5-10% faster is simply not worth gaming on an outdated 40nm card.
Also, you might love your massive OCs, but some of us run at stock to enjoy the 100% stability without effort.
The whole point of overclocking is to exceed stock specs but maintain 100% stability. Since when is running gaming benchmarks and Unigine Heaven for a couple hours "effort"? You make it sound as if overclocking of a videocard and stability are mutually exclusive. The fact of the matter is people have been running overclocked 670/680/7950/7970 cards for the last 12-18 months. Considering 7950 MSI TF3 6+8 pin versions have been rocking 1100-1200mhz+ GPU speeds and matching/beating GTX680 since last summer when they cost $300, it's impossible to be excited about 760Ti for experienced PC builders.
Even if we look at it from a point of view of stock performance, GTX670 fell to $330-350 so many times over the course of the last 12 months, that it makes no sense why anyone would wait 12-15 months to save another $30-50. If so little money was worth it to wait another 12 months to them, they shouldn't be buying $300 videocards in the first place.
The other thing is HD7970 1Ghz cards are dropping to
$350.
Looking at where a 1.05ghz HD7970 stacks up in frame times against GTX680/780/Titan in latest games, the HD7970 1Ghz card looks like a way better "bargain" than a hypothetical GTX760Ti:
There are
a lot of games where a 1.05 Ghz 7970 levels the 670 by 20-30%. $50 more & 3GB of VRAM, great overclocked scaling and free games would make it a lot better value than a $300 760Ti in the first place.
When we look at $300 GTX760Ti ~ GTX670 vs. $350 HD7970 1Ghz, the 760Ti is way too expensive given the huge performance delta between them.
HD7950 needs a price drop now that 1Ghz 7970 cards can be found for $350. Comparing GTX670 to HD7950 V2 no longer makes sense considering that a $350 HD7970 1Ghz would be barely slower than a $450 GTX770 4GB card and that a $350 HD7970 1Ghz wipes out a 670 without effort.
In fact, it takes a 1250mhz GTX670 to match a stock 1.05ghz 7970.

And that's months ago. Since then AMD's drivers have only improved further.
