It looks pretty solid, only thing I would recommend is getting an Intel CPU. The AMD processors in general are not recommended for use with game development; I used to have an AMD FX-4100 on my old PC and thought that was decent simply because it was a quad core, but I realized it really isn’t capable of much. Today, I have a i7-4770K which is vastly better than the processor I had before. If you have the time to wait, then I would suggest you save up a little more to get a better processor like the i5-4570.
Take a look at page which compares all the top-tier CPUs to date. ://www.cpubenchmark.net/high_end_cpus.html
