nForce4: PCI Express and SLI for Athlon 64

Final Words
nVidia did quite a turnaround with the nForce3-250 chipset family back in April. The nF3-250 updated the much-criticized original nForce3-150 chipset and moved what had been the worst of the Athlon 64 chipsets to the front of the Athlon 64 pack. The plethora of new features that were introduced with nF3-250 have proven to be useful and reliable over the last six months. nVidia also navigated the move to Socket 939 in the nForce3 Ultra version without any glaring problems. The on-chip Ethernet, hardware Firewall, solid PCI/AGP lock, and "any-drive" SATA/IDE RAID have been well received in the market and remain as desirable today as they were 6 months ago.It is not a surprise, then, given the massive updating that went into the nForce3-250 chipsets, to find the nForce4 more evolutionary than revolutionary. The new 4 name is certainly justified by the addition of PCI Express and SLI capabilities, but nForce4 is still underneath the excellent nForce3 Ultra chipset that we have come to trust. Except for PCIe and SLI, the new features generally refine those first seen in nForce3-250, and that is a good thing. The RAID controllers are now faster, more flexible, and even easier to manage than the last generation. The nTune Performance Configuration Utility does more, and does it better, than the previous utility, and 10 USB 2.0 ports must be better than 8. The performance also breaks no new ground, nor did we expect it to. The nForce3-250 was very fast and the nForce4 is just as fast, but not really any faster than the nF3 Ultra at this point.
The major new features, PCI Express and SLI, are the real sizzle here. It is difficult to argue with what appears to be a very successful move by nVidia to PCI Express, even if there is really no current performance advantage that we could find to a PCIe video card compared to the same card in AGP clothes. Certainly, the potential for better performance is there, and nForce4 certainly protects the end-user for a while longer from video card obsolescence.
However, nForce4 is exciting mostly because of the incredible performance potential of SLI, which combines two top nVidia video cards into a monster video performance engine. It's not for everybody - SLI is undeniably expensive - but the prospect of a 40% to 85% leap in the performance of the most demanding games that you can run today will be too much for some enthusiasts to resist. No, you don't absolutely need SLI, but it sure is cool! Consider nForce 4 an evolution and refinement of the progress that nVidia realized with the nForce3 Ultra, and that's a very good thing indeed.

I'm going to back people up on the annoyance of not having soundstorm or atleast something about the audio system. Any nforce2 owner knows how good sounstorm is, i've got an audigy2, and any non EAX source goes through soundstorm for me.I can't believe for enthusiast motherboards, they are touting features like firewalls, 90% of us use routers, its just not that exciting anymore.
Disapointed.

I think I read somewhere (probably The Inquirer) that nVidia isn't including Soundstorm cos they don't want to pay for a Dolby Digital licence or something.If people don't like the onboard solution, they can just slap an old Sound Blaster Live in the system for peanuts. I do that and it keeps me happy.

dude, where is my soundstorm?This is a rip off to the general consumer, and would have hoped that Anandtech would have picked up on it and made a mention of the problem --
What doesn't nvidia get? there is a huge demand for soundstorm.
Nforce4 is a step back from all the other chipsets in terms of audio.
Intel is pushing hi-def audio, via has got its ENVY series, why would nvidia leave out soundstorm
boooo nforce4
booo Anandtech for not pickup on this

One more thing,Would all the monitor hookups on the cards be active. That would be great cause you could put to gether quite a nice 4 monitor workstation for pretty cheap. you could get those 2 6600GT's and 4 Viewsonic VP171's for about ~$2200. No more expensive then a high end 20"-23" display, and a lot better picture and performance and space (564 square inches vs only 373 for an apple 23" HD Cinema).
Just wondering.

holy crap i want one so bad.BTW, if any one wants a nice big tax write off, my college TV station is looking to replace our PII and PIII video editing and station machines. So if anyone has some extra hardware laying about.....
(No joke, we really, really need new gear).

wait a min,I've seen benchmarks on the web for NVIDIA SLI cards. I don't remember which exact cards were used, but I do remember that one ran in a 16x slot and the other ran in an 4x slot with a 16x connector.
The point, the 4x slot has more than enough bandwidth because it worked perfectly. With no perfomance loss.
Wish I had the link somewhere.
So any chipset that supports pci-e should handle sli just fine, as long as the mobo maker puts two physical 16x slot connectors, regardless of their actual bandwidth.

Will mobo manufacturers increase the possible Bus speeds? Please say yes, I would love one but I want to get to 290... Page 7 says max is 250, that is not ok..plewis00 - Tuesday, October 19, 2004 - link
Can you run, say a 6600GT and 6800 Ultra in SLI? Seeing as they are both Nvidia and the SLI connector should be in the same place?
