You're welcome... so good for your psu is it 80+ bronze ore more ? otherwise even at 3,8-3,9 ghz i think you couldn't be able to notice any changes (through naked eyes) through any games except enabling the fraps soft which allows you to see at he fly the fps (5 fps more at 3,9-4,0 ghz)... in fact overclocking makes difference when the frequency is very high (at least +25-30% added to stock speed) and through particular programs like zip, encoders, movies/photos makers, games and of course benchmarks... but above all overclocking is for fun and psychological for certain persons
