Picking the mobo

I'm looking to build a new system and need some ideas on a new mobo.
Other components:
Amd 64 X2 5600+ Brisbane (2.9GHz)
Corsair (2 X 2Gb) 240 pin 800 DDR2
Seagate Barracuda 250Gb 7200 rpm 3Gb/s SATA
Pioneer 20X DVD+-R DVD Burner
2 X Ati Radeon 4850 Pci ex 2.0X16
Aerocool Masstige Silver SECC .8mm Atx Case
CORSAIR CMPSU-750TX 750W

So as you can see i want something that can take all these parts, and it has to be good with crossfire. I might overclock it, but probably not much so thats not a big deal. Ive been looking at the 790fx line and have come up with these two boards so far.

http://www.newegg.com/Product/Prod [...] 6813131291
http://www.newegg.com/Product/Prod [...] 6813136044

What i like about them is they have all the stuff i need, at least one extra pci ex 2.0X16 slot, and are in the 150-200 dollar price range. In addition they have very high customer ratings compared to many other mobo's.

So, which would you say is the best choice, the cheaper DFI, the more expensive ASUS, or something else other than those 2?

You can disregard the above post. These are clearly Crossfire boards and either would suit your needs. Some people need to read the specs before posting. This is from the Newegg spec sheet:

"4 x PCIe x16 with ATI CrossFireX support, @ dual x16; tripple x16 / x8 / x8; or quad x8 modes
Support PCIe 2.0 / 1.0 Architecture "

Dual x16 crossfire support -

Suggesting an x38/x48 board for an AMD build? Really!?

Never mind. The post was edited to reflect a valid recommendation.

fleakiller's original post stated "these are not crossfire boards more for sli, look into x38/x48 chipsets"

I was leaning towards that one myself, but only because of the 4 pci ex 2.0X16 slots and the fact that ASUS has a good rep. Does anyone know if either have any issues fitting stuff on the board?

Thanks for the links fleakiller.

I have some questions for anyone just to clear up some things i read on newegg reviews.

Does the ASUS board really require a floppy drive just for the installation?

How bad is the high pitched noise made by DFI boards?

Do the heat pipes/pci slots on the ASUS board get in the way of vid cards?

Is the DFI board really cheap quality?

Is the ASUS bios actually bad, or is there online support to make up for it?

Does the DFI board also have things in the way of vid cards?

Are most of the customer's complaints result of them not doing enough research or just being dumb?

As for the floppydrive it is if you are going to set up a raid drive http://en.wikipedia.org/wiki/RAID , As for the DFI i do not know , the heat pipe will not get in way of video card but might get in the way of some afer market cpu coolers, the dfi board i do not know i have never owned one, as for the asus bios it is the same as any other bios some times they need to be updated (If you are have problems and the update is to help),and once again i have never had a dfi board but i would think that it would be the same as asus with cpu coolers (after market), as for the quad cores duel will be faster in some games but a quad core will last you longer in my opinion. hope this helps
