That's rather interesting to have 2 PCIe 2.0 and 1 PCIe 1.0 connected to two different chips. If there is a latency issue with 780i and 3-way SLI, how big of a latency would there be?
- "The problem is that two of the PCIe 16x slots are PCIe2 and one is PCIe1. Hmmmm. The PCIe2 slots are connected to the north bridge via a chip called the Nforce 200 bridge chip. This is rumoured to be one of the things they still haven't managed to get completely functional yet.
The one 16x PCIe1 slot may or may not be connected to the south bridge, the diagrams are purposely misleading here. In the end, you have 2 PCIe2 links 2 hops from the NB, and one PCIe1 link one hop from the SB.
See a latency problem?"
