Help choosing board

Last response: in Motherboards

I am buying a new board but for now, I don't want to upgrade to any of the ddr3 motherboards. I am going wait for the new amd chipsets to mature a little more and then I will upgrade to something better next year. I just purchased a 4890 for a good price and i wanted to buy a second one to crossfire.
Right now i have a m3nht deluxe 780a sli mb and I also have 8gb of ddr2 1066 memory installed. I wanted to get a cheap board with a amd chipset that would allow me to crossfire a couple of 4890 in 16x16 and also use my 8gbs of ddr2 ram. Does anyone know any good board for under C$150.00 ?
I was thinking to get this one but it only does 16x8 in crossfire I think:

Gigabyte MA790X-UD4P ATX AM3 AMD790X DDR2 CrossFireX 2PCI-E 2PCI SATA2

Any suggestion will be appreciated.

Thanks. :)

To be honest, the 8x/8x Crossfire ability probably isn't going to handicap you too much with 4890's.

I went from a 16x/16x SLI motherboard (with a Q6600 @ 3.2Ghz) and upgrade to the i5-750 (@4Ghz) with an 8x/8x board and my 3dMark scores for GPU actually went up pretty substantially. (Using 2 GTX 260 Core 216's)

The 16x/16x motherboards are going to be more expensive, and if you're hoping to use this as a temporary board I don't think you're going to miss a whole lot.

What clock speed is your Phenom 955 BE running at? You may see more performance difference simply by having a higher clock speed on your CPU than you would see difference between 16x/16x and 8x/8x for those video cards.

Phenom II 955 3.2 ghz 31C idle water cooled.

Yeah you are right.
I will probably get the Gigabyte board.

Yeah, at 3.2Ghz you probably won't get those 4890's to cough up 100% of their capability. I apparently didn't with my Q6600 @ 3.2Ghz, and that was with 16x/16x. You should be good to go.

That Gigabyte board should be a fairly good board for the money. :)
