CPU poor Proformance

[falconmick]

I have found of recent that allot of my games are not running as fast as they should and that the playback of 1080p is poor (having to pause to re-buffer) So I decided to try and find the issue...

I believe that It is something to do with my CPU as my keyboards CPU usage indicator tends to reach near 100% as my games as such as COD 4 start to lag (My PC used 2 run COD 4 fine) even now on minimum graphics COD 4 runs at first at 90FPS then down to 14-23 FPS as the CPU gets above 80-90%

So I ran an overclocking program, and according to that my FSB of my CPU was running at 2000, where as a E6750 should be at 2660 Hz, How Can I solve my issues?

If you want my full DxDiag, PST me.
