why 3 PCI-E slots?

[vinnypolston]

I just bought my EVGA 122-CK-NF63-TR LGA mb and noticed that by the specs it has 2 PCI-E 16X slots (for SLI). what exactly is the 3rd PCI-E slot for ( says 1 x PCIe Graphics expansion slot )

I'm a little confused on this...

If I am running SLI what good would a 3rd card do me? unless..

run two identical cards in SLI for gaming
and run a cheap Quadro card for video editing?

and is that possible? to have two displays.. one from the sli'd cards and one from the quadro?



ugh, so confused, please help me understand...

thanks,
-Vinny





:EDIT:

upon further reading I found out that it is meant for physics processing ( both ATI and nVidia have something in development ) ..

since mb are already being sold with three PCI-E slots you would think either ATI or nVidia would be getting close to releasing something but I can't seem to find any new up-to-date info on it...

anyone else know anything?

There are other PCI-E cards, too. SCSI/SAS, Serial ATA, ethernet, etc.

SLI/Crossfire + Physics is still vaporware, though AMD was at least showing off a supposedly working Trifire setup. There still isn't any game announced that would use such a solution for physics yet.

ah, alrighty. thankyou much!

hopefully, someday they'll release something..
