Good build, nice deal on that combo, but i wouldn't get that motherboard. I would also consider the phenom 940BE since it can overclock easier, but that combo deal makes up for it, great savings there. Great choices otherwise.
What is your budget?
I would look for an all AM3/DDR3 build. A WD Black drive will be faster.
I would prefer a mobo by Gigabyte, ASRock, Asus, or Biostar over MSI or Foxconn, and those over what's left. You're getting a GPU; if you think you may want to use Crossfire, get a 790GX board, otherwise get a 785G.
Good PSU. Big enough for Crossfire, or get a 750W model for even more headroom.
I like this wireless card: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It has mixed reviews at Newegg, but I had zero problems with mine, and it was a big improvement over the b/g card it replaced.
