Low CPU and GPU usage.

The reason I have been having low random gpu usage drops and random fps drops recently is because I am bottlenecking. Usually I'd be playing a game just fine for a bout 5 mins straight when suddenly I get raped. These drops usually last for about a minute and my GPU usage will drop from 90% or so to 40% or so. I haven't monitored my CPU usage much during playing but during the drops my cpu usage will drop as low as 10%. I have an AMD phenom 965 BE, nVidia GeForce gtx 460, 4gb, ASUS m4n68t m v2, and a 650w power supply. Should I up the voltage on my CPU or something? There is no reason my cpu should be bottlenecking any nVidia card. I've checked my temps and they are ok. I've tried a few different driver versions, overclocked my cpu and gpu, tried gaming with default clocks, boosting up textures, lowering textures, lowering resolution, and boosting resolution. This has been happening on all games and is extremely gay. During the drops The game becomes all skippy and ***. Even though I'm running about 65-100 fps during the drops.

Single player games or online? If online might be network or server lag since your specs look fine! CPU voltage is hardly going to fix the issue.

Another issue it can be is if you run out of memory it will have to reach into the pagefile on you HDD which would create lag. If you have many background processes that would be a possibility.

I have no background processes. 4gb is more than enough for games like cod4 and waw.

What exact PSU do you have? Could have power dropping under load.

I would think that would hold up, but you never know. Have a spare psu to try out?
