Nvidia GeForce GTX 680 is on the way to balance up the next-generation graphics market.Most Awaited Card by Nvidia is here .The Nvidia GeForce GTX 680 is its latest $400-odd, top-of-the-line card and is now the fastest graphics card in the world.
Anand Tech gave the GTX 680 a clear 5-20 percent edge against the HD 7970 in most recent games, with "wholly unexpected and completely stunning" leads as high as 28 percent in games like Battlefield 3 and Portal 2.
The card even kept pace with the Radeon HD 6990 and GTX 590 -- not bad when you consider that those dual-GPU cards burn around 30-50 percent more watts. Overall, AnandTech says "this is by far the easiest recommendation we've been able to make for an NVIDIA flagship video card."

Hot Hardware : showed that the new NVIDIA could only be beaten by dual-GPU cards in 3DMark11, had lower power consumption under load (and similar consumption at idle) compared to the 7970, and concluded the GTX 680 was "the fastest single-GPU based graphics card we have tested" and "another win for the consumer".
The Tech Report :put the GTX 680 "just a couple of ticks" below the HD 7970 in its particular "99th Percentile Frame Time" test, due to higher frame latencies in some titles, but indicate that the $50 price advantage, lower power and quieter operation more than make up for it.
Hexus : gives props to the GTX 680's "super-funky" GPU Boost technology "that helps keep the card working at near-maximum potential at all times", and also points out that the card readily overclocks to deliver a 15 percent lift above stock performance in Crysis 2, leaving the GTX 590 in a cloud of dust and the 7970 in quicksand. On the other hand, "AMD's not far behind" and "we eagerly wait to see what happens to Radeon HD 7970 and HD 7950 pricing in the next few weeks."
Tom's Hardware : GeForce GTX 680 employs two six-pin auxiliary power connectors. Those two inputs, plus a PCI Express slot, facilitate up to 225 W of power delivery. Nvidia rates this card for up to 195 W. However, it also says typical power use is closer to 170 W. Keep those numbers in mind—the available headroom between 170 W and the 225 W specification ceiling come into play shortly. Nvidia claims it put a significant effort into three aspects of its dual-slot cooler’s design, contributing to an impressive acoustic footprint, even under load. We can peel back the GTX 680’s shroud for a closer look.Nvidia says it added acoustic dampening material to the fan motor—a step it also took with the GeForce GTX 580, which contributed to getting that card’s noise level down compared to its maligned predecessor.
