keep in mind that APU work best with fast rams
skip the 1333 and go for 1600mhz or more
(1866 or even 2400mhz will be awesome)
also, you dont ned the 6670 to tell the true, APUs A10 are awesome :)
save cash for buy a big GPU in the future, insted the 6670
(i recomend min one 7850, then the 7870 LE or the 7950 if you reach)
Good luck on your build
