For a gaming build you want to spend more on graphics and less on CPU.
You are most likely to be better off with an AMD build, though an Intel i3 build is economically viable.
Your build looks great provided it's for general desktop use. You could even drop your PSU to 450W and the RAM to 1333MHz and not notice any difference provided you're not gaming.
If the PC is for gaming, it needs a bit of a rethink. Post back if it is.

Yeah for sure, an i3 with a basic H81 motherboard is going to be similarly priced or a bit cheaper, but I think the AMD option is the stronger all-rounder, and the one to go for at this price bracket.
