Ok just to ask, I noticed that from reading the manuals of these boards Asrock 990FX Extreme 9, Asus Crosshair V Formula Z, Asus Sabertooth R2.0 (990FX), Gigabyte GA-990FXA-UD5/7 all have PE slots that half their bandwidth when their lower slots are occupied. Only the Asrock 990FX Extreme 4, Fatality Professional, Fatality Killer and Gigabyte GA-990FXA-UD3 do not. I know AMD hasnt jumped on the PE 3.0 Spec but Id like to in the future maybe run 2 cards in crossfire at the full capability of the slots. Also the Asus and Gigabyte boards only have a 8+2 Phase, where the AsRocks have a 12+2, Im thinking for the FX ud want the 12+2 Also on another Note- the 8350 is within my range(Cant find a 8300 at all- perhaps yall have a good place to find them). 9590 is just way too out of my range to build on.
