I tried searching but could not find an answer. What's the easiest way for me to have two profiles on my Vista PC for overclocking and non-overclocking. When I play games, I want to overclock, otherwise I don't want to overclock (and possibly underclock the GPU). What's the best way for me to do it? Can I have a dual boot (both into the same Vista installation) but one use an Overclock BIOS and another using a regular BIOS configuration? Or is there another way to accomplish this?
