Can I DIY a QUAD SLI using two of the cards mentioned on a regular SLI mobo? Like the Gigabyte-8N-SLI Royal? It run as quad-sli with those two cards in it? Or is some Nforce chip missing from the system? Big cheers.
It's possible, but current drivers won't run it.
You can do it but there are driver issues in quad SLI sistems. You need to wait.
