Can somone answer an sli question for me?

Ok how does pcie sli work with the sli bridge? You have one 6800 in the pci-e slot and the other 6800 connects where?
Do you have to have a dual pci-e x 16 slot board or is that just the simple way of doing it?

Yes you have to have a dual pci-e 16x board. You cant just use anyboard for SLI. It has to be one specifically made for it. Right now there are no Intel boards out that support it. So unless you want to wait for one or decide to goto AMD your stuck with your setup.

You have it backwards. There are no amd boards out right now, only Intel boards are currently available with new nforce boards comming out very soon.

There are AMD SLI boards out now. Goto newegg and search for an Nforce 4 board. I believe Asus and Gigibyte both have ones out curently that work.

Thats the link for the 2 SLI boards. Intel currently does not have SLI because nvidia cas not made any nforce boards for Intel yet. Untill Nvidia does that SLI will stay a AMD thing.

I believe it was intels tumwater chipset that was the first board to handle sli, that was before the NV boards were even sent out to reviewers. The link you posted shows a navagation error btw.

Is SLI available on Intel based PCs?
Technically, yes. You can do an SLI system on the Intel 7525 "Tumwater" chipset based server boards which have two physical PCI Express x16 connectors on them (most limit one slot to x4 performance). However, these dual processor based boards require expensive server parts that are not appropriate for gamers or enthusiasts. Xeon processors, Registered DDR memory, and the boards themselves all add up to a hefty pricetag.

Is one of the very first sli systems available to the market.
