[H]ard|OCP recently tested the highly overclocked MSI GTX 680 Lightning, but because of the new release of the MSI Afterburner 2.2.3 tool they decided to retest to see if the new Afterburner will raise the ceiling on their maximum overclock.  This new version allows voltage control of the GPU, the memory, and the PLL which ought to help push the card to higher frequencies.  That did certainly turn out to be the case as they saw noticeable increases to all of the clocks on the card and more importantly translated into improvements in game play.  When they used the LN2 BIOS the improvements were even more impressive.  Remember that volt modding will shorten the lifespan of the card, but what a life it will have while it survives.

"Today we are revisiting the MSI GeForce GTX 680 Lightning video card. with its long-promised GPU and RAM voltage tweaking Afterburner software. We test both the stock BIOS and "LN2 BIOS" to find the best possible gaming experience the Lightning has to offer, and determine if the performance justifies the price."
