this is the most precarious install you'll ever make, if this goes wrong there is usually no way to re-flash.....
if you OC quite heavily this is quite good for adding additional options, if not i'd leave it well alone......
if you want to update the BIOS make sure your running ''optimized system defaults'' when you do so.... if you update over an exsisting OC you'll bugger it.
are you going to do it via USB..??
