Motherboard suggestion

I have the following system

EVGA 790i Ultra SLI mobo
Intel E8400 processor @ 3.0 (Will OC this soon)
4 x 2 GB Kingston HyperX memory, 1600 MHz
3 x 750 GB WD hard drives (Will probably get raptors in Raid in the future)
9800GX2 video card(can't remember the manufacturer)
28" Monitor Hannspree @ 1920 x 1200
Vista Ultimate 64 bit
Logitech Z - 5500 5.1 Speakers
Asus Xon

I am thinking of getting a 4870X2 or maybe two of them and run them in crossfire so I need a new motherboard. I'd like it to have the following:

DDR3 memory
2 PCI-E 16X running at 16 X
be a great overclocker
crossfire compatible

What do you recommend?

anything that is from asus/gigabyte/dfi with x38 or x48 on it...

Give it a few more week or so (if you can) and the Asus Rampage Extreme should be out...its the same as the rampage...X48 chipset...with DDR3 support and a few other add ons...(Asus already has support listed for the RE on there website)

Asus Rampage Extreme

I plan on getting that board shortly after its release...I have high hopes that it will be just as strong, if not stronger, then my rampage formula...
