Can't speak for the NVidia club, but I've tuned lotsa AMD video card bioses. At least with the program I was using, you could make fan profiles each state of the card (like high load or no load or middle load or what not) you could change the voltage for each state, the speed of each state, quite a bit of control when you think about it. That was back when I was mining, and you want things to run overclocked and undervolted with heavy fans to hold the heat down. Haven't played with my 290Xs yet, just gaming on a 1080p, so plenty fast. The reason to do it to the card bios is so you can run different cards in one machine and still get the control, else, afterburner works too, though, not as reliably from my experience. With the...

Most people don't just make new BIOS-es... they simply use one of the freely available utilities to *modify* the official BIOS with a few things. You can usually overclock more when you give more voltage to your graphics card; of course, this is not to be messed with unless you really know what you're doing, too much voltage can easily fry your card or make it overheat.

With the overclocking info on the card, you can move it from one machine to another too without having to overclock again, one and done.
