You should pick an i3, the fm2 is a dead socket and you'd have no clear upgrade path. If you got an i3 you could get hold of an i5/i7 and get a decent performance boost at a later date.
It makes no sense to buy an APU if you're buying a graphics card, if you were stuck with fm2 you should buy an Athlon (basically an APU with no GPU) and use the money saved to get a better GPU.
Basically the APU is a wonderful concept but doesn't work in practice, it was priced too highly vs a cheap CPU and GPU for only a little bit more money.
