I have a friend who is running an(my) fx 8350 using a dev build (4.0-5954) and he plays monster hunters tri, SSB, xenoblade and fire emblem and he says he runs all those games at full speed 30/60 fps. If you want I can go over to his house and actually test xenoblade myself and I do have super mario galaxy so I could test that as well. If there are any other games let me know if I have them I will test them.
