I got an Intel E5700 with Asus P5G41T-MLX motherboard. In the BIOS, there was an automatic overclocking option. I selected the '10%' option and my CPU was overclocked till 3.3 Ghz on air. I played 'The Witcher' for an hour without any issues (the Trade quarter has become much smoother now). Should I go further? Can anyone give some advice?
