Also, some don't have the option of flashing to an unlocked BIOS, or don't know how to, and I don't wanna be responsible for breaking people's computers. If they wanna overclock, by all means, they can. Via software, we don't have any responsibility over someone if they bork their computer by overclocking. If we release a driver, and it doesn't allow overclocking via software, and tell them to flash their BIOS and overclock, we have a bit of responsibility there, and I can't be held responsible for that.
It's just better to be safe than sorry, and wait for a driver that supports software overclocking. I'm watching the situation like a hawk.
