Nvidia GeForce GTX 680 Video Card Preview @ Ninjalane

Nvidia claims that the GTX 680 is the fastest and most efficient GPU ever built and evidence of this can be seen in almost every aspect of the video card. In terms of efficiency we can contrast the older GTX 580 and can see a 50w drop in TDP giving the GTX 680 a clear advantage in power consumption. Combine that with the performance enhancements of the Kepler core and you have a GPU we can talk about.
