I would look into finding a different mobo i would not use a 8320 on a board with a 4+1 power phase you probably want at least 6+1 unless you want to use the 8320e and no overclocking
Your cpu will bottleneck your gpu. I love amd but this is true for bigger gpus. 1 7200 1tb hdd will be enough for recording and playing its quick enough. Get 2x4 gb ram instead. Personsally. Use the money you save from 1 less hdd and some other ram and get a i5. I love amd so fanboys dont hate on me.
