PSU? Please state brand, model, wattage and efficiency rating (none, bronze, silver or gold).
Other than that, nothing wrong with it. I can only suggest a cpu cooler if you're actually using the stock one, as AMD CPUs tend to get quite hot compared to Intel ones. I own a Cooler Master Hyper 212 EVO and it's pretty much awesome for what it costs. I actually have an Intel i5-4670, but the hyper should be AMD compatible too...you might want to check that out by yourself, just in case.
Don't take as a given you can max out everything however...it always depends on how good the game is pc optimized and AMD GPU optimized, in the end. As an example, I currently own an Asus R9 290x DCUII OC; on a 1080p resolution, Titanfall runs maxed out at averagely 100 fps, and Borderlands 2 does the same with physx set to medium (low would make it jump to at least double that value), but Watch_Dogs struggles at keeping over 60fps while running at medium-high settings...
And no, I won't pretend they won't "mess" it up, as they always do
