Doesn't it make sense?
It makes perfect sense, but my benchmarks heavily disagrees with that point. Running at 1346mhz consistently gives better results than running 1359 and throttleing to 1346. Often it is not only the clock that is throttled, but also the voltage (atleast in my case, i use a multimeter for voltage readings, the voltage fluctuates a lot, as soon as my card starts to throttle, i wish i had 50 different 670s/680s so i had real evidence in my claims). My advice is, that if you can avoid throttleing, do so.

Even if I set the clock to 1202 (boost) she will throttle all the way down to 1110 and 90mhz drop.
This only happens with the modded KGB bios, so as you said could be a power thing, with stock bios it only throttles at 13Mhz at a time.
Sadly, i don't have that issue myself. How much of an increase in real-life performance do you see from overvolting? I use a 670, and the difference between 1297 and 1359 is almost negligible, compared to the voltage increase (1.75 to 1.26), and if it wasn't because of my e-penis, i wouldn't run it any faster than 1297-1310 :S. I can only say that i am truely disappointed by the performance of a triple slot cooler.
