....if there is an online guide to what the diffrent features are in SLI and how to implement them??? I have SLI, but under my global settings, it has things like "transparent AA" and multiple modes for that one selection......I have no clue what that is. If you have a link, that would be much appreciated. Thanks.

AFR - Alternate Frame Rendering - Card A renders one frame, then card B renders the next, and so on; this is the setting used for most games

SFR - Split Frame Rendering - Card A renders half of one frame, while card B renderd the other half (balanced so that the load on each card is equal); this setting works better for some games.

SLI AA - SLI Anti Aliasing - Uses the second card for AA purposes, allowing you to use up to 16X AA

TSS AA - Transparancy Supersampling - This is a method of AA that works on alpha textures, but slows performance. Use in games with lots of alpha textures (these include chainlink fences, powerlines, trees...etc)

TMS AA - Transparancy Multisampling - This is a method of AA that works on alpha textures without the performance hit of supersampling. It is less effective that SS, however. Use in games with a lot of alpha textures when supersampling is too slow.

You shouldn't have to change the AFR/SFR settings, as the latest drivers come with profiles for hundreds of games that automatically choose the best setting.
