Steady 1200mhz core clock, hitting up to 60c, 60.1fps at all times. I Googled it and found that it locks your settings in to place and tells your GPU that it's not supposed to be in word-processing mode. I poked around in the settings and saw the 'EVGA K-Boost' under a slider where I could mess with the voltage.

In-game (Battlefield 3, Skyrim heavily modded, Portal 2, Crysis 2 - all at or beyond highest settings) my GTX 670 was taking a nap it was mostly running at 100-200mhz below its core clock speed, using 30-40% power, hitting 40c max, etc despite being overclocked in Precision X. That's when I opened up Evga Precision X and decided to utilize its built-in monitoring features. Earlier today (12 hours ago) I was getting frustrating lag and stutter in Portal 2 when I knew damn well (see signature) that my rig could handle whatever was thrown at it it never lets me down. I'm sorry if it seems like I'm exhuming a thread from last month but I wanted to throw my hat in the ring on this amazing subject.
