According to the review: turbo boost is 1.1ghz application specific, bf3 and uni. It comes with Nvidia adaptive v-sync. Capable of 4 monitors or Nvidia 3d Vision surround 3 display on 1 card. faster than 7970, $559, runs cool. 294mm2, 3.54 billion tranny, 195watt.
beats amd on performance per watt and performance per mm2
New aa method is called Nvidia TXAA. Authors opinion is 7900 should go from 550 to $350.

"Launched a new "Kepler," GPU microarchitecture, using 28nm process by TSMC "GK104" graphics core to make the opposite. Click. The first models will be "GeForce GTX 680, the number of new the SMX's CUDA Core, up to 1536, and joined a large number of Fixed the Function of the Hardware Block for TDP with the new GPU Boost technology to enhance the efficiency of Rasterization, the Shading, texturing, and the inventor of the GPU, the Compute The power to make dynamic overclocking, what the new "The GeForce GTX 680" Can beat "Radeon HD 7 970", become the overlord of the new generation of high-end graphics card?
Practical function open: new antialiasing technology TXAA
In addition to the graphics performance, NVIDIA also for the needs of gamers, add a number of new and useful features for a new generation of the GeForce GTX 680, released a new anti-aliasing technology TXAA, a new generation of hardware rendering anti-aliasing technology, actually belongs to the old MSAA's enhanced version provides better anti-aliasing I can reduce the open antialiasing fluency decline, for the time being belonging to the GeForce GTX 680 unique anti-aliasing, but NVIDIA said that the above will be open at a later time to the GeForce GTX 500 or Model.
TXAA temporarily can be divided into two levels: TXAA 1 and TXAA, the former costs only 2x the MSAA similar, but the MSAA is better than the 8x anti-aliasing; As for TXAA 2 effect is more outstanding, but the cost only similar with 4x MSAA. TXAA game itself support to be open to use, support TXAA variety of games will be held during the year stage, although present, failed to test its real performance, but based on the NVIDIA official photos can be seen, antialiasing does, it is worth looking forward to.
In addition to the new TXAA Antialiasing, NVIDIA is also an existing graphics card users to bring good news, the introduction of the original few games before the corresponding FXAA to the NVIDIA Control Panel, users can easily turn the feature on. lead to better anti-aliasing for different games, and enhance the quality of the game screen.
TXAA provide better anti-aliasing for images I can reduce the performance degradation brought about by the anti-aliasing. (Can enlarge)
NVIDIA has FXAA introduced to the NVIDIA Control Panel within convenient to open home.
New Adaptive VSync technology
NVIDIA, on the other hand, made for the actual operation of fluency of the game is optimized and to promote the new Adaptive VSync VSync setting are gamers, open the main purpose is to reduce the graphics card output image is generated in different fps too fast or too slow situations, and the output frame rate is locked in with the mainstream display screen 60fps. However, the image of the actual output of the graphics card will still be due to different scenes within the game for differences between the actual output fps lower than 60fps fps, will be directly reduced to 30 below 30fps is reduced to 20fps.
In fact, such cases are quite common, and convert 60fps to 30fps of the screen will significantly slow the beating, which greatly affect the fluency of the game, the new Adaptive VSync just solve the problem, when the Adaptive VSync enabled, the system automatically detection of the actual operation fps than 60 VSync will open a locked 60fps output frames, such as less than 60 will be automatically VSync turn off and running to the actual output frames to reduce all of a sudden dropped to 30fps from 60fps is the emergence of slow beat, can be very useful.
Adaptive VSync solve the traditional VSync problem dropped to 30fps, 60fps, slow beat.
Adaptive VSync has been added to the NVIDIA Control Panel within.
NVIDIA 3D Vision Surround support single-card three-screen output
For the practical application of the full range of the GeForce GTX, 500 series or the previous product, the core of integrated video signals, limiting the single a graphics card can only output up to a maximum of two screens, three-screen output to be run in SLI mode. flexibility weaker than rival AMD Eyefinity, but in order to combat AMD Eyefinity technology, NVIDIA is also a lack of existing products to enhance the flexibility of the multi-screen applications.
GeForce GTX 680 graphics cards support single card with two DVI and one HDMI output of the three-screen and 3D Vision's way to reach the NVIDIA 3D Vision Surround restrictions without the use of DisplayPort, flexibility even more than the AMD is better The DisplayPort interface, of course, users can also connect an additional display to the graphics card, four-screen output to the "3 +1" program, a single card."
