hmmm... interesting but misinformed. The attitude reflected in your post towards pricing is typical of people that justify overpaying based on current prices (btw, did you invest in the stock market at its peak as well, just before the crash?). First, there are much cheaper nforce4 mobos already available, for exampe Foxconn board in the UK for
48 pounds, and soon enough it will be available here, and many more like it. Second, the same nfocre4 chipset is used for SLI or non-SLI, so the only difference is handled by the mobo manufacturer, by configuring and putting in an additional x8 pci-e channel (the actual sli operation is handled by the graphics drivers). Third, once retail prices for sli mobos come down to reasonable levels (e.g. close to the wholesale prices), it would in fact be quite possible to build a cost effective system, and have sli as a great upgrade option in the future.
Hahahahaha. Overpaying? Since when is $119 for an ultra nforce4 board overpaying? As for stock market, nice way to stereotype a person. For your info, I don't play the market like that. I invest in a couple blue chips and then let my money sit for 10 years or more. Less profit, but also much less risk. You have to decide your own risk you are willing to take and invest appropriatly. But isn't this off topic?
I wasn't aware of the Foxconn motherboard, but you sure do lose a lot of features for that $92.24 (per the xe currancy converter) as compared to the $119 which is less than $30 additional. And I'm not sure I'd call them 1st or 2nd tier either.
It only has 2 dimm slots, only 5.1 sound, only 8 usb ports, only 2 pci slots, only 1 pci-Express x1 slot. And of course the ultra features as ppl have helped me figure out above, which are missing active armor, slower hyper transport, and no 3GB sata.
As for your claim of the Nvidia SLI chip version being the same as the ultra chip. Well not according to what I see on nvidia's pages:
http://nvidia.com/page/nforce4_sli.html
" the unique single-chip, low-latency architecture of the NVIDIA nForce4 SLI MCP"
"NVIDIA nForce4 SLI MCPs include dedicated SLI hardware"
Then on
http://nvidia.com/page/nforce4_ultra.html
"NVIDIA nForce4 Ultra MCPs (media and communication processors)"
"With NVIDIA nForce4 Ultra MCP"
and on this page:
http://nvidia.com/page/nforce4
"NVIDIA nForce4 MCPs"
etc. Oh one more quote "NVIDIA SLI certified motherboards include NVIDIA nForce4 SLI MCP"
You get the idea. There are 3 seperate versions of the nforce chip, they have 3 differant spec sheet pages.
BTW, you do NOT get "an additional x8 pci-e channel" on the sli as that quote from you states. And if you did it would have to be supported by the nforce chip, you can't just throw something like that on without chip support. If you bothered to do a modicum of research you'd notice this.

Lets get some linkage to backup my claims since you probably won't belive me.
Exhibit a)
Nvidia's Nforce4 Ultra Specs
"PCI Express Configuration 20 lanes Fixed (16,1,1,1)"
Exhibit b)
Nvidia's Nforce4 SLI Specs
"PCI Express Configuration 20 lanes Flexible"
Well well well. Exact same number of lanes! But but, does this mean that SLI has to share the 16 lanes and do like 8 each to a SLI card? Yes.
Source:
http://usa.asus.com/prog/spec....%20Deluxe&langs=09
"Expansion Slots - 2 x PCI Express x16 slot
*SLI mode : x8 , x8
*Default(Single VGA) mode : x16, x1"
You can also check reviews on various SLI motherboards, most of them state something about this.
Another quote from nvidia SLI FAQ
"SLI technology requires a PCI Express motherboard. Current configurations support motherboards with two x16 physical connectors. The graphics cards plug into these connectors. The cards can work with whatever routing because x16 PCI Express connectors can auto-negotiate down to x8, or x4 electrical." It might have a physical 16x but in SLI mode it runs at 8x each. Now does this really matter currently? Probably not, I doubt the current PCI E cards take full advandage of all 8 lanes, let alone 16 lanes. I mean look at IDE hard drives, they are barely moving into ATA 66 sustained territory right now. They might need more for some bursts, but sustained they aren't even close to using ATA 133.

You can see in PATA that the sustained transfer rates start at around 33 on inner tracks and go up to 56 or so. On SATA it isn't much better. 38 to 65.

Because of all of this and the additional complexity of most SLI motherboards, the extra cost of the nvidia SLI chip, and the added card thingy that most motherboard makers seem to be using right now for SLI, I dont think you'll see a SLI motherboard lower than $200 for a while. So back to my starting point. I think that overpaying would be paying $300 for an SLI, not paying $119 for a ultra.
" Third, once retail prices for sli mobos come down to reasonable levels (e.g. close to the wholesale prices), it would in fact be quite possible to build a cost effective system"
Sure, and thats why I said "But currently the very high SLI mobo costs makes that impractical. "
Notice the use of the word CURRENTLY?

If it was say only about $50 more for SLI, I would be seriously looking into it for a possible upgrade path. But its currently much more. So currently, you are probably better off buying a ultra nforce4 and spending the extra you would have paid for SLI on a better graphics card. Unless of course you have tons of extra money and want to SLI the 6800 ultra, in which case the cost isn't a big deal.
