ABSOLUTE GAMING BEAST

Nvidia's geforce gtx 680 is by far the most powerful and energy efficient graphics card ever built with a little add on features which you are already aware of  like gpu boost 2.0 adaptive v sync etc as nvidia has already introduced these features in their previous models on, pc, notebook, and at mac book as well
1- It is based on kepler architecture which is  more advanced than the gcn or (graphics core next )
architecture since it gives more performance at same power
2- It comes with 1536 cuda cores with a base clock speed upto 1006 mhz                                                                                                                 boost clock speed upto 1058 mhz
                                                         max resolution -4096x 2160
                                                         bandwith 19 gb/s
 3- It comes with a memory inter face of 256 bit gddr5
                                           power consumption 550w
4- Now to consider an amd card of 2k bucks more  budget that is at most 19,000  amd hd 787O                                                                                                                  1- clock speed -1056
                                                                                                 2- max resolution 2560x1600
                                                                                                3- 256 bit gddr5
                                                                                                 4   16gb/s
                                                                                               5 power consumption 630 w                                                        SOOOOOOOOOO GO FOR IT GUYS U WONT GET A BETTER BEAST AT 16K BUCKS
                                                                                             

g sync

Well we all now about nvidia's  adaptive v sync technology which helps us to plat high end as well as low end games at decent fps depending on your geek                                                                                               but now nvidia has decided to launch a new wirless networking  v sync which is being called g- sync or game stream technology  in the recent montreal summit ceo of nvidia  JEN HSUNG HUANG announce it can  really prove to be a great step towards networking gaming not only that even nvidias new project sheld is also being equipped by it

nvidia what is this name

NVIDIA awakened the world to computer graphics when it invented the GPU in 1999. From our roots in visual computing, we’ve expanded into super, mobile and now virtualized computing. NVIDIA's mobile processors are used in smartphones, tablets and auto infotainment systems. PC gamers rely on GPUs to enjoy spectacularly immersive worlds. Professionals use them to create visual effects in movies and design everything from golf clubs to jumbo jets. Researchers utilize GPUs to advance the frontiers of science with high-performance computers. And the introduction of NVIDIA GRID™ and GPU virtualization delivers visually demanding applications from either on-premise or cloud based virtualized servers  .
U WILL BE SURPRISED TO KNOW THAT 
1- FOR LAST 4 YEARS EVERY FILM THAT IS BEEN NOMINATED FOR THE BEST VISUAL EFFECTS CATEGORY HAS BEEN MADE USING NVIDIA QUADRO TECHNOLGY
2- THE WORLD FASTEST  MOBILE GPU IS NVIDIA TEGRA 4 PROCESSOR
