looks good to me, thats a nice ps and should handle that graphic card easily.
the temperatures seem normal to me and voltage doesnt seem off.
i think ur ready to go.
also u might wanna consider cheaper just as good alternatives:http://www.newegg.com/Product/Product.aspx?Item=N82E16814202006
such as the 7950 witch is a bit stronger and similar price, also comes with 3 gigs of ram instead of 2.
def a nice card.
nvidia is nice but ati can do just as good and somethimes cost a bit less.
