Hello.
I am getting ready to purchase all the components for my build and I have switched back to ATI because the prices of nVidia cards are not declining as much as I'd like them to.
But anywho, I was wondering if I could do 3 way Crossfire on this motherboard. It says 4 PCIe 2.0 x16 so that means it can handle 3 video cards right?

Heres the video cards:

Thanks in advance.

It says tri-cross fire @ x16 / x8 / x8, it wont be using all 16 lanes across the 2nd and 3rd boards, but x16 vs x8 some say is negligible. Crossfire is meant to work with 2, 3, or 4 boards. It should work as long as your PSU is strong enough.

Thanks for the reply.
I was wondering if you or anyone else knew of any other motherboards that would handle tri crossfire and a phenom x4 processor.

I think your biggest issues might be with HIS quality. As an owner of an HIS card, I can say with great certainty that I will NEVER buy an HIS product again.

I would recomend this http://www.newegg.com/Product/Product.aspx?Item=N82E168... just because it is cheaper and the performance gain is minimal and the cooling solution is good on this card. I do not own HIS card but I just hear here and there about quality of his ^ agree with hairycat

There are no motherboards that will do Tri-Crossfire with all three cards running at X16. Anytime you go over two cards Crossfire will be cut back to X8 no matter which board you buy. The Asus board will run 3 or 4 cards in Crossfire but at X8.

w153r is completely correct. I use the board with two 4870's in Crossfire and it works great and does work with the Phemom and with BIOS 504 or 602 will work with the new Phenom II 940 or 920 and will also work with the Phenom II AM3 cpus when they come out as well but only with DDR2 memory. One point on this board, if you get one I suggest you DO NOT use Corsair memory on the board. It is listed on the Asus web site as fully supported by the board but many, many people are having problems getting it to work. You don't have to take my word for it, just go to the Asus support forum for the board and read the storys yourself. Some users are going thru 3 to 4 sets of memory before finding a set that will pass memtest on the board.

When did the x58 boards start using Phenom CPU's? Isn't that sort of like trying to put a square peg in a round hole?

Sapphire has 2 years warranty. Asus has 3. Visiontech is supposed to be lifetime. I've heard visiontech doesn't always find a way to void that, but they try like hell. I would do Sapphire or Asus or even Powercolor for my next ATI card.
