On a motherboard, what specific slots do you use to put it in SLI? I've seen boards with PCI-E x16 and then a PCI-E x1, and I want to know what the x1 is for. Do you need two PCI-E x16 slots, one of x16 and x1, or a x16 and something totally different? Sorry, just a bit confused on this whole SLI idea. If anyone knows how the crossfire works, that'd help too.

PCI-E x16 is almost exclusively used for graphics cards, whilst the x1 slot is for other less demanding add-in cards such as GigaBit Ethernet adaptors, TV Capture Cards and the like. That being said, there are a small number of PCI-E x1 graphics cards available, however the performance of said cards is usually abysmal compared to their bigger brothers.

As for SLi, you just need a SLi compatible motherboard, two identical nVidia GPUs (6 series or higher AFAIK) and a decent PSU. You then connect the two cards using the provided 'SLi Bridge', which is a small connector that fits over the top of both graphics cards.

CrossFire works in exactly the same fashion, except you need a CrossFire compatible motherboard instead, as well as two CF-compatible ATI cards. Older CF setups used an external cable to connect the two cards (one of which had to be a special 'Master Card'), newer ones use a 'CrossFire Bridge', which is essentially the ATI equivalent of the SLi bridge. The CrossFire Master Card is now redundant.

Me too. :p

They sure don't seem to be in any big hurry to start pumping out much of anything in the pci-e x1 or x4 format. Aside from the ppu's, for now it's mostly a waste of space. I hope Vista can usher in a new tech era forcing people to upgrade out of the antiquated technologies.

As far as I'm aware, PCI-E 1x is pretty much identical to PCI in terms of speed and the like. And the fact remains that pretty much every PC out there has at least 1 slot, most AGP and some early PCI-E 16x systems have 4 or 5. The amount of PCI-E 1x slots is far lower, even though pretty much every mobo on the market comes with one.

I have seen PCi-E TV cards, network cards and one sound card, but it's worth noting that it was a professional card costing something like £900/$1800. So not your bog standard Creative XFi lol.

So it is just two PCI-E x16 slots? As I said in another forum, I'm trying to build a Conroe Mobo PC and I've hardly seen any really good SLI boards for it.

Core 2 Duo + SLI = the uber nForce 680 or slightly older and less uber nForce 570.

Well, could you give me some mobos off Newegg that are $160 or less that are good SLI and Core Duo boards? I've searched forever and it's hard to find them.

Well $160 completely eliminates the few 680 boards lol. They cost about $250 minimum.

Open box, but right on your budget - http://www.newegg.com/Product/Product.asp?Item=N82E16813131071R

Minus some features, and probably safer as it's new - http://www.newegg.com/Product/Product.asp?Item=N82E16813131032

Mm, that sucks. Is the 680 really that much better? If I buy an outrageously expensive board like that will I see a huge or fairly substantial jump in performance? If I do buy a $250-$270 board, that will take my price in to the $800s.

They are very nice boards but no, I seriously doubt they're worth the extra money. Like all new tech, they're overpriced and there aren't many of them.
