2) I checked prices of PSUs. You can get a Corsair 500 for the same price as the 430. The one I linked is a better choice cuz it has a little extra power in case you buy a discrete GPU in the future, and the PSU is semi-modular which means the cabling in a small case will be easier with this PSU. http://pcpartpicker.com/part/corsair-power-supply-cx500m
What resolution are you going to game on? If you are using 1366x768 then you should be able to run BF4 at maybe Medium settings. and the same with the other games.
Your rig has a decent processor, but the graphics are going to be pretty limited on that APU. If you're ok with lower settings, and not necessarily playing the next gen games, you'll be ok. If you want better performance, you want a discrete card.
