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:
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.
