Hmmmmm...  this is wierd, the MSI specs for 780i board shows  2 PCIe 2.0 at (1x16+1x8)
when the EVGA 780i shows both at x16. either a typo or MSI is cutting edges . The EVGA boards
are alittle more in cost, but I like. I have the 680i A1, works great. Plus EVGA gave me a lifetime
warranty on the MB and both 8800gtx's.

There's a new driver at nvidia 174.74, but it's beta all tho I'm hearing good things about it.
might try it, but who wants to do beta testing yuck.  8-)
