I was looking at this MB but I could not find any reviews yet.

Intel(r) DX48BT2, X48, Socket-775, ATX, DDR3, 1600MHz, GbLAN, 3x PCI-Ex16,...

http://support.intel.com/products/motherboard/DX48BT2/index.htm

I'm looking to get a new MB with 3 PCIe slots to get 2 4870's as soon as they are out next month and then a 3th 4870X2 when it get available. This way I get quad crossfireX without having to trow out the single GPU cards that are supposed to be released first.

Does anyone know other MB's with 3 PCIe slots for crossfireX with 775 socket for Intel?
I mean fast ones like the Nvidia 780/790i series.

On the Intel site (link above) I don't understand the speed of the 3th PCIe slot, is it fast enough for graphics or not?

This is a copy/paste:
Two PCI Conventional* bus add-in card connectors (SMBus routed to both PCI Conventional bus add-in card connectors)
One primary PCI Express* 2.0 x16 (electrical x16) bus add-in card connector
One secondary PCI Express 2.0 x16 (electrical x16) bus add-in card connector
One PCI Express* 1.0a x16 (electrical x4) bus add-in card connector

Any advice would be appreciated.
I'd build a gaming machine the a new peryn quad, probably the Q9450 or Q9550.
But in a way I'd prefer the extreem Q9650 but it seems so expensive for just a higher clock and unlocked multiplier.

I did some googling and I think I found the aswer would be only PCIe1.0 at 4x so not enough for good gfx.
I found the Asus Maximus extreem board with X38 has the second and third slot at 8x, but I guess even that would not be ideal :-(
