We'll test the EVGA GeForce GTX 680 Classified today. A product that is 100% customized from PCB to cooling. Software voltage regulation works, but obviously as well is limited to that 1.175V. EVGA however does have an alternative for the Classified model as tested today, you can hook up a small piece of hardware to it called EVBot, which controls the voltages directly at hardware level, and thus bypassing the NVAPI software limitation.
Hi-hoo 1400 MHz, here we come ! Read the review right here.
