Conclusion: Nvidia has introduced some impressive innovations in its new single-GPU flagship card, the GeForce GTX 680. Hard-core PC gamers shouldn't expect down-the-board AMD-crushing frame rates, but reduced power bills are a distinct possibility.
Pros: Amazingly power efficient. Excellent performance. Reduced profile. Supports four monitors, 3D Vision Surround on one card. Requires only six-pin PCIe power connectors.
Cons: Not always appreciably faster than competing AMD card. Blocks an expansion slot. Requires a hefty power supply.
AMD Radeon HD 7970 GHz Edition vs. Nvidia GeForce GTX 680: frametimes review
25 February 2013
Excerpt: A few days ago we introduced you to the concept of of frametime tests, a more accurate way of gauging graphics card performance in video games. Today we are applying the new test for the first time, and with the new data we will compare the AMD Radeon HD 7970 GHz Edition to the Nvidia GeForce GTX 680.
Excerpt: Late March Nvidia introduced its latest flagship graphics card, the GeForce GTX 680. By now a number of cards have been released that are based on Nvidia's reference design. Hardware.Info compared seven models to find out which is the best buy.
Summary: The GeForce GTX 680 is the fastest single-core graphics card produced by Nvidia, and it is one of the best high-end graphics cards available on the market. The Kepler architecture makes it easier to run the most demanding games on high and ultra settings, and it is sure to unlock the best your games and videos have to offer.
Pros: This card has a 1GHz base clock speed, has a high memory bandwidth and runs games effortlessly on high and ultra settings.
Cons: The GTX 680 is a long card and only has one HDMI connection.
Summary: We evaluate overclocking performance of the new NVIDIA GeForce GTX 680 video card. Can we can squeeze any more performance out of the 680 that GPU Boost isn't already doing on its own. We compare to a standard GeForce GTX 680 and Radeon HD 7970. We also compare both video cards at the highest overclocks head-to-head.
Conclusion: Until then, as promised, you can find our interview with Tom at Nvidia where he does a live demo with the on the fly overclocking and GPU boost and to top this off heres a link to our Palit GeForce GTX 680 2GB graphics card review
Excerpt: We’ve been hearing about NVIDIA’s Kepler architecture since about September 2010 . It was back at that years’ NVIDIA GPU Technology Conference, that company CEO Jen-Hsun Huang first publically disclosed that Kepler would offer massive performance per watt improvements over Fermi and previous-gen architectures and that GPUs based on Kepler would arrive in 2011. Well, the launch date has obviously slipped. How Kepler’s power efficiency looks, we’ll get to a little later.
Pros: Great Performance, Relatively Cool and Quiet, GPU Boost, Adaptive VSync, TXAA, 3D Surround From a Single Card
Cons: Expensive (Although Priced aggresively), Additional Considerations for Overclockers
NVIDIA Kepler GeForce GTX 680 SLI Video Card Review
28 March 2012
Summary: We've got two GeForce GTX 680 video cards to test SLI performance against Radeon HD 7970 CrossFireX. Will these less expensive GTX 680 video cards offer a better gameplay experience or choke at high resolutions due to a smaller VRAM footprint? We will prove to you which solution offers better efficiency and performance.
