Do you need that mb?

Feature wise its a great AM2+ mb and would let you crossfire a second gfx card . But you wont need to do that any time soon with a 4890 and a 22 inch monitor .

If you are not intending to add a second gfx card you could move to an all AM3 build for about the same price

With a Gigabyte GA-MA770T-UD3P $189.96

G.SKILL 4GB kit (2GB x 2) DDR3-1333 (PC-10600) CL8-8-8-21 MEMORY $155.21

I think thats a little bit cheaper than your am2 build, and should have a longer working life with more parts support . Performance will be very similar

You do lose the second gfx card slot on the mb though

Is there any MBs that you would recommend that support Crossfire and DDR3?
I looked at the MB you mentioned and apparently needs VRM heatsinks if you are planning to OC and trying to find heatsinks in NZ is a nightmare and the Asus MBs look alright but it seems a bit of -tive and +tive comments.

Ideas?

And reason for Crossfire is that I plan to keep this system for over a year so would like the option of crossfire.

^ you also have the crosshair III and one by DFI.
