regardless the board looks awesome! I am still on the sabertooth x58 as my 24/7 rig. its a very solid board. but its just no Rampage in terms of ocing.
I hope some day we see some dedicated x8 pcie slots for the high end raid cards. It sucks that I have to plug a x8 raid card into a x16 slot and them my x16 slot for the video is running at 8x pcie/ or I plug the raid card in the bottom slot that is physically like a x16 slot but it runs at 4x.
so no matter what you lose bandwidth. what is the chipset capable of supporting? does anyone know the 990FX bandwidth of all the x16 slots? is it x8/x8 or x16/x16 or x16/x8 16x/4x? just curious.

the northbridge has 38 pcie lanes for slots (x16/x16/x4/x1/x1), another 4 for the southbridge (x4) and the southbridge offers another 4 x1 lanes :up:

the X16 slots can be devided into 4 x8 slots and all slots are pcie 2.0

oh crap.. so you are saying if you have crossfire/sli you are already using 32 lanes so you have 6 left? plus 4 off the south. can the south share lanes off the main 38 or is it that bogus 4x slot at the bottom again?

if you have those 2 main x16 populated what is that x8 slot actually running at? thats what I want to know.

From what I have read abot this board, the first slot is always 16x, the next black slot is 4x connected to southbridge, then you have two which can have split bandwidth 8x/8x, or 16x/1x.

there is alot more flexibility in the chipset

cou can run the northbridge in:

x16/x16/x4/x1/x1
x16/x8/x8/x4/x1/x1
x8/x8/x8/x8/x4/x1/x1
x8/x8/x8/x8/x1/x1/x1

afaik it supports up to 7 slots in all possible combinations (the southbridge supports another 4 x1 slots)

most higher end boards switch from x16/x1/x16/x1/x4 to x16/x8/x8/x1/x4 when you plug in an x8 or x16 addin card into the 3rd x16 slot the same goes to the 4th slot (x8/x8/x8/x8/x4)

990fx has 2 times more lanes than sandy bridge and the same amount as X58
