If you are overclocking your card at all, i'm not sure why you would want to give up the control of setting your clock to a specified number. If you crank the volts and clock to 1200mhz, you're already pushing the card beyond stock clocks. If boost were enabled at those clocks it would try to set a clock that requires more voltage than can be supplied resulting in a crash. This is probably why Sky doesn't even bother releasing a bios with boost 2.0 enabled as it just results in crazy instability. Boost 2.0 is designed to work within a set of parameters (stock clocks, stock voltage headroom). When you change those parameters (increasing clocks, unlocking voltage) boost becomes unreliable and unstable.
Regardless, the point of overclocking is to get your card to within 5-10mhz of instability. WIth that purpose in mind, boosting becomes pointless as you want to always be running at that frequency and anything higher is unstable anyway. Don't mistake gpu boost with down clocking.... the gpu will still down clock when idle without gpu boost.
IMHO if you are overclocking, it's in your best interest to use Sky's bios and get rid of boost. IF you want to use boost, don't overclock... that's what the tech is designed for... an on the fly, no thought involved overclock from stock settings.
I can see where you're coming from bud, but i overclocking with keplers is great because it's in the mode of offset, not fixed.
In other words, its like an intel CPU. When you change the offset, you actually change boost frequency parameters just like an Intel CPU using Speedstep. Boost 2.0 does work absolutely fine with offset overclocking, in my honest opinion, Boost 2.0 is best enabled with a higher TDP power target.
I love playing COD Blackops 2 graphically maxxed with 120FPS and my GPU sitting at 880Mhz, i thank Boost 2.0 for that.
