Maximum PC: Today the embargo lifts on the second GeForce GTX 700 series GPU to be announced in a week's time; the Titan-cooled but GK104-powered GeForce GTX 770. Unlike the GTX 780 announced last week, this card does not use the monstrous GK110 GPU, but instead opts for a highly-clocked version of the GK104 chip found previously in the GeForce GTX 680, GTX 670, and GTX 660 Ti. It's the highest clocked-part of all of those cards though, and also has 7Gb/s memory instead of the 6Gb/s variety found in all the previous Kepler cards, giving it a signficant bump in memory bandwidth.
HardwarePal: After Nvidia launched its flagship graphics card the Gtx780 for the 700 Series, they also launched the Gtx770 later as a cheaper alternative. The Gtx770 is not actually a new model ...
tbh for me with 670 there simply isn't enough of an improvement to justify the upgrade and the price hike doesn't help
I have 2 Gtx680's in my current pc , it would be a waste of money even for Gtx780s.
HotHardware: It was just last week that NVIDIA launched the excellent GeForce GTX 780, which is essentially a scaled-back GeForce GTX Titan, at much more palatable—but still relatively high—price. NVIDIA is not quite done making news, however. As is typically the case when NVIDIA launches a graphics card in a new product family, derivatives that continue to flesh out the product stack are soon to follow. First came the GeForce GTX 780 and today marks the arrival of its little brother, the GeForce GTX 770.
BenchmarkReviews.com: NVIDIA's GeForce GTX 770 video card is built from the 28nm Kepler GK104 graphics processor, identical to the GTX 680 released back in March 2012. Featuring 1536 CUDA cores that are clocked to reach 1085 MHz using NVIDIA Boost 2.0 technology, GTX 770 also comes with 2GB of GDDR5 video memory that creates the world's fastest 1753 MHz graphics frame buffer. In this article, Benchmark Reviews tests and compares the NVIDIA GeForce GTX 770 graphics card using several highly-demanding DX11 video games, such as Metro: Last Light, Batman: Arkham City, and Battlefield 3.
