yes the classified will run like that but so you know the difference between running x8 and x16 is not gonna be noticeable in the real world it only shows differences on benchmarks.
My setup will be running 2 x16 + 1 x8 + 1 x1 (all in the pci 2.0 slots) total = 41 lanes.
This means that I will be using 41 lanes in the pci-e 2.0.
Intel says that I can use up to 36!
If that is true then my setup will be something like this:
2 x8 + 1 x8 + 1 x1 = 25 lanes
(1 x16 + 1 x8) + 1 x8 + 1 x1 = 33 lanes (SLI running one card at x16 and the other at x8 if that is possible)
Is that correct?
