Yeah, doesn't make sense for nVidia's 780i to not support Yorkfield. I have great reservations that Intel would cook this up just to get back at nVidia and completely alienate a subset of its customers.

680i may be different, but it claims on eVGA's site that the 680i boards WILL support 45nm CPUs with a BIOS update, but obviously the BIOS update to ACTUALLY support the CPUs is forthcoming, not here.
