:lol: wow, thats a pretty wierd build...here are my suggestions, then i will show you a build:
CPU:you might want to invest into a quad core ...also, this cpu is the higher clocked version, and gaming gets more help from higher frequency.
MOBO: i would recommend trying to get a 790x or 790gx board, rather than 785g.
RAM:
...well...first off, amd boards are meant for dual channel, so you get 2x__ kits, not 3x__ second, dont get 1 gig sticks, get a 2x2 kit for the 4 gigs.
CASE: might wanna get a more quality case...
PSU: the case part isnt that serious, you can get away with a less than reputable case, but with PSUS, YOU CANNOT!!!! spend the extra little bit and get a good one!
HDD: ??? you realize that you can get a hdd...
