Hi All 
Read this for the best video performance...hmmm not sure about it
....YOU????
This comes from the Geforce 'Point of View site'.
Strange, they tell you that you must set your AGP just to only 2x even when you have a Geforce TI4xxx???
******************************************************************
Hardware Settings
Set the AGP aperture size to the total Memory on the Video Card. For example, if you have a 16MB video card, then set the AGP Aperture size to 16MB. If you get strange or unexplained lockups, set this to 4MB and move it up one step at a time to find if any of these settings fix the problem.
Lockups tends to indicate system RAM or a system that is not implementing the AGP Aperture size properly. Lowering the memory timings as well as the memory bus speed may help.
Just as a test, Set all the configuration parameter to its minimum setting the system allows on the motherboard BIOS setting.
BIOS Settings
The BIOS checklist below assumes that you have installed the latest BIOS from your motherboard maker. If you have not, or are unsure of how to check or how to update your BIOS, please contact your motherboard manufacturer for assistance.
At boot-up, go into your motherboard BIOS, this is typically done by pressing the DEL key or the F1 key at startup - but some motherboard will vary, so if these don't work, contact your motherboard or computer vendor for assistance.
Take some time to look around and familiarize yourself with how the BIOS is laid out and what the different controls are. When you are ready, set as many of the BIOS settings that you can find to match the list provided below.
If you make any changes to your motherboard BIOS, please note them down as you make them so that you will be able to change them back if they create more problems.
Also, please be aware that there is no industry standardization for BIOS. Each one is written specifically for one model of motherboard. Because of this, it is almost impossible to guess which category a given feature will be in, so you will need to look carefully. Also be aware that not every feature listed here will be available in every BIOS, and not every BIOS will call them the same thing. So just be aware that you may need to make some educated guesses. For example: AGP Turbo Read Mode: Enabled (found in one motherboard bios) is actually the same thing as AGP Read WS: 1 (found in another motherboard bios). If you have questions about what different settings do, contact your motherboard maker or your BIOS maker.
