GTX 780 Overclocked beats R9 290X Overclocked. Dealbreaker for you?

There's a target frequency (the max) and it clocks down towards a minimum frequency to compensate for heat. In other words, it's underclocking.
It is determined by a hard limit, though. The only difference is that AMD is displaying a particular variable in the boost table that the card can't go past, no different than the peak kepler boost for the card, instead of the base clock. Kepler boost will not continue to boost past that peak clock unless you manually unlock the voltage, which just raises it to another clockspeed in that table, and another hard limit.
The boost table for Kepler cards is even calculated from the maximum value. It doesn't overclock from the base value, it throttles from the maximum value, with a hard limit at the base value.
For safety reasons, it won't allow the card to operate above a certain voltage, but the logic behind it is still throttling from the set peak value.
Hell, with boost 2.0, I'm pretty sure you can even turn off the base value and allow it to throttle right to the minimum value in the table.
And for that matter, there's even a value within the bios to control maximum allowed boost besides voltage. AMD's boost can be perfectly replicated with Kepler Boost parameters and logic.

Damn, I missed a single space.

One thing is steering me away from the 290X. High temps. Don't care if the card was meant to be run @ 95C... just too warm for me to consider. Especially as I would want to crossfire them eventually and having 2 super hot cards in one case doesn't sound like a good plan. Now, my options are single 780SC with option to SLI later, SLI 4gb 770s or crossfire 280X. Waiting to see if prices come down around black friday to pull the trigger.

Linus said that they actually tune down the fan until it hits 95. Maybe they are aware that their cooling solution is so dang loud. Regardless, I'll wait for non-reference.
