If you buy an AMD APU, you're paying extra for the integrated graphics compared to an equivalent CPU-only chip (e.g. Athlon x4). Given that you're buying a discrete graphics card and won't be using the iGPU, this is a waste of money.
As said above, even the best CPU available for that mobo isn't very good. The CPU you selected there is very weak. I know you said you're planning on upgrading the mobo/CPU, but I don't understand why you'd dump money into a new build with the intent to upgrade, but buy a dead-end platform that requires you to replace everything when you do upgrade. You're much better off in the long run spending a bit of extra cash now to get something with an upgrade path.
