I've got a GTX 680 SC+ (1050 ghz)... but when I run precision X (eVGA) it shows it running at 324MhZ .. occassionally jumping to 1050 for short periods of time. Considering I run two clients of a game, and I am noticing some less-than-desirable results... what is wrong? Is this normal, or should I be changing some settings?
Make sure you're running the latest 304.79 beta drivers. There is a clock bug in the earlier drivers.
Also be aware that your card will dial clocks up and down in response to idle, 2D, or 3D load demands. With a 680, you will also get Turbo Boost clocks on top of that when gaming. As long as you're not at 324 mhz when gaming you should be good. Hopefully it's 1006 mhz minimum while gaming.
