Hey i going to be buying this build very soon http://pcpartpicker.com/uk/p/z0Gm and im just wondering if this overclocking tutorial is good and 100% working http://www.youtube.com/watch?v=ZmgTv5nwBu8 because i watched other tutorials and you have to go into bios etc and here its just one program that does everything and that's a bit suspicious but i don't know thats why im asking you lot Thanks
