Any of them will do, but not for SLI.
For that you may look at this:http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010200022%20107193049&name=NVIDIA%20nForce%20900
To me its not worth it, but any AM3 board should have PCI-E 2.0 X16. So it will accept one nvidia card. You need to make sure the board can handle the power requirements of the hexacores. I would look at the 870, 880, and 890 chipset boards.
