nForce4: PCI Express and SLI for Athlon 64

DX8 and OpenGL Gaming Performance
It is amazing to see Quake 3, one of our oldest benchmarks, perform extremely well on the PCIe video card. Return to Castle Wolfenstein, the other OpenGL benchmark, also performs better on PCIe, but not to the extent of Quake 3.
Another real surprise in the PCIe performance results was X2, a DX8 game that is heavily dependent on Transform and Lighting effects. PCIe results were significantly higher than AGP scores.
Other DX8 results were a wash comparing AGP and PCIe results on the FX53.

I think that it has to be two Nvidia cards with an SLI connector. You are thinking of the alienware video array, which theoretically can use two different branded cards.GhandiInstinct - Tuesday, October 19, 2004 - link
Wesley,So in SLI, I can put any two video cards together? No matter the spec difference or maker difference? New and old? Future and past?

I take it the SLI benchmarks from nVidia were done at about 1600 x 1200 resoultion?Wesley Fink - Tuesday, October 19, 2004 - link
Kris -Anand and I got some hands-on time with the SLI system while we were visiting nVidia. The benchmarks we ran confirmed the numbers reported for the 6800 Ultra single and SLI. The test system was an Asus SLI motherboard with a 4000+ CPU. While we did not personally run benchmarks with the 6600GT SLI or the 6800GT SLI we have no reson to doubt nVidia's numbers based on what we did confirm.
The Reference board is NOT SLI, which is why SLI testing was limited to our time with nVidia.

#6 those are NVIDIA's benchmarks, not actual 3rd party confirmed benchmarks.Kristopher

#2 and #4 -SLI Performance tests are in a table on page 3. Two 6600GTs don't outperform a 6800 Ultra, but they do outperform a 6800 GT.

#4, from what ive heard, it is probablyh likely that two 6600GTs would definetly cream the 6800 ultra. I do agree that we need some SLI benchies!!!ariafrost - Tuesday, October 19, 2004 - link
*Drool* Anyone know how much of a performance boost would come from SLI yet? I'm wondering if two 6600GTs would outperform a 6800 ultra.glennpratt - Tuesday, October 19, 2004 - link
Page 2"While nVidia was not ready to ship nForce4 SLI reference boards for review, they were demonstrating a major manufacturer's nF4 SLI board with a pair of nVidia 6800 Ultra video cards. We also got to play with the SLI system with an Athlon 64 4000+ CPU, confirming benchmarks that were supplied by nVidia."

why didn't anand did any SLI performance test? i thoguht this board suppose to have SLI.
