SLi x16 improves performance for SLi.

The quick take-away from the performance metrics we've laid out with the ASUS A8N32 SLI Deluxe is that in standard business, desktop publishing, content creation, and multimedia applications, this motherboard has all the horsepower of other motherboards based on NVIDIA's original single-chip nForce4 SLI implementation. However, the real sweet spot, as we expected, appears when running the board in high-end gaming applications in multi-GPU SLI configurations, and more specifically SLI-AA modes, where the board outpaced the standard ASUS A8N SLI Deluxe by as much as 58% - 67%. The benefits of dual X16 PCI Express graphics slots are not fully realized, however, until requirements for PEG link bandwidth are increased, as is the case with the data-sharing requirements of NVIDIA SLI-AA. Standard AA modes running in SLI showed much less significant gains.

However it provides a little/or no performance increase in normal AA. But SLi AA looks much better so it might be worth it to some.
Discuss.

Looks good Cookie, good find. Adds a piece to the puzzle, will make SLI AA more of an option on newer games.

Off Topic: In the new 81,85 beta forceware driver, the mysterious NV48 is still alive, 7800GS is going to be released soon (bit slower than the 7800GT).

Edit- the driver fixes alot of problems.

NVidia is quoted in the article as saying: "Future scenarios with lots more geometry being passed to GPUs, a lot more textures, SLI-AA, and so on, will see more improvements over time."

Sounds great to me. Now if they would only enable SLI for Linux....
