Powertweak is the premier processor and chipset optimizer there is. Each processor/chipset configuration will have its own optimal settings, so experimentation within Expert mode is encouraged. Warning: do not disable the cache!
If you aren't sure which of the settings to use, go into the optimization menu and click "Optimize for speed." This will enable all of the enhancements that are available for your system. You may have to go out of expert mode to perform this.
Note that the No Lock feature won't work on some PII based processors (all 233~266 MHz models, as well as the older 300~333 MHz models) - but the setting is not detrimental to those systems, so try it out anyway.
General Video Card Tweaks
Particularly when dealing with 3D rendered games, the speed of your video card can be very important. There are a few general tips that apply for all 3D cards. First, begin by downloading and installing the most recent drivers. This is a particularly important step for video cards because of the vast changes in the drivers between versions. I personally recommend using the reference drivers from the chip manufacturer, and not the drivers supplied by the board manufacturer. Reference drivers are frequently newer and faster than the drivers that the board maker can supply, because they base their drivers on the reference drivers.
Also, it is imperative that you only run your desktop in 16 bit color, even if you are running 3D programs in 32 bit color mode. The only exception to this rule is when dealing with some OpenGL games that do not have the ability to dynamically change the bit depth of the screen. Changing the bit depth of the screen can be done through the Display applet in the Control Panel.
