When it was first reported that nVidia SLI supported FutureMark 3Dmark05 and 03, many gamers considered the support something of a joke. But as you can see in the benchmarks, both 3DMarks are very good at demonstrating the potential impact of SLI on gaming performance. Moving from single video to SLI increases 3DMark05 performance by almost 80%. Similarly, we see a performance increase of over 60% in 3DMark 03 when we compare results with a single video card to SLI. Aquamark 3, another "standardized" 1024 benchmark, also sees improvements with SLI, but they are much smaller than the huge performance gains in the 3DMarks.
Doom 3, Half Life 2, and Far Cry all follow patterns that we have seen in their performance since SLI was first introduced.
We purposely included a few benchmarks that we knew were not supported by current nVidia drivers to show what can happen in these games. SLI results in these non-supported games range from no improvement at all with SLI to small performance losses in Quake 3. The point is that SLI is only worth it if the game you want to play is supported by nVidia drivers. This may get a little more complicated if nVidia turns on SLI by default when the driver sees an unknown, but for now, you need a supported game for SLI to make sense.
Yes, we fully expect the new, exciting, and best-selling games that are on their way to be supported by SLI.

whoops no mention of psu was used in system config listing but didn't read till page 20 of the review it mentions OCZ 520W PS psu hehSlaimus - Monday, February 28, 2005 - link
They used a OCZ 520W.neologan - Monday, February 28, 2005 - link
I think the test results for 3dmark2003 single and SLI are the wrong way around?http://www.anandtech.com/mb/showdoc.aspx?i=2358&am...

Why did they show no benchmarks with the mobo's overclocked? It doesnt make sense to say these boards are better becuase you can clock the memory higher if the overall CPU clock is roughly the same. The reason they dont show you is that due to the onchip memory controller on the AMD chips, the high memory frequency doesnt make much of a difference at all in real world terms. As long as you can clock the CPU high that is all that really matters. Also they dont take into account cost as some boards cost 50% more that the others.dornick - Monday, February 28, 2005 - link
I was considering jumping on the SLI bandwagon until I had some sense knocked into me.I'd like to see a comparison of the Ultra chipset MBs, including the Chaintech, Epox, etc... since that's where I think the nForce 4 market will go.

missing one vital piece of info, what PSU you used heheSpacecomber - Monday, February 28, 2005 - link
Thanks for doing the indepth analysis of this new chipset and how it is being implemented by some major motherboard manufacturers.There was one detail that I was hoping to see some reference to. I understand, from a friend, who has the MSI SLI motherboard, that the Creative Live sound chip only works if your power supply has a -5 volt connector on it. It looks to me like the OCZ power supply that you used has this, but many of the new power supplies, such as the Enermax v2.0 power supplies, no longer have a -5 volt connection. He was using a Enermax 535 watt Whisper II (SLI ready) when he ran into this issue. This kind of compatability problem slipping through QA seems like another indication that the everyone was in a big hurry to get these motherboards to market, maybe before they were thoroughly tested.

I liked the subtle hints Wes.In your final words you stated, "If you want the best performance possible then the answer would likely be yes". Then how would this apply for users getting two 6600GTs?

great articleminor gripe -- the overclocking "graphs" are useless -- what would be better is the resulting fps of overclocking to show people if its worth it to get that extra xxx fps

now i am waiting ultra mobo benchmark. What about the price of all this mobo ? i fell disappointed with msi doesn't have PCI 1x. (Sorry my english language is very bad)
