In general, if there is any gaming involved using discrete graphics I normally recommend going with AMD's APU. For all the other things you mentioned either CPU should be fine. However, I am unsure of how well the integrate Intel HD graphic core will handle Blu-Ray movies since they do require a bit of decoding by the graphics cards. The Intel HD is less powerful than the Intel HD 2000.
+1 for the AMD APU. I went A10 in the end.
My needs are similar to your, but I want to game a little bit also.
