i have had this pc for about a month, and only just started looking at its features. i really like the screen, for monitoring the system.
so far i havent really played with the overclocking, but it is really easy to go from default speed and settings to the overclocked one you want. e.g. to get turbo on, middle botton right botton right botton than middle botton. (press the right button until u get to the settings you want if you want something other than turbo.)
to change the o/c settings in windows there is a icon on the bottom right that has guru clock, black box, flash menu, oc guru and abit eq. and it is easy to change everything, as long as you know what you are doing (which i still learning to do)
