gaming server build

Nice parts..
except your mobo..
Asus M5A78L-M/USB3 Micro ATX AM3+ with 760 chipset is very low end motherboard, and will not able to overclock your processor on it..
even at stock clock, you'll suffer performance penalty..

get a better mobo..

Something like asus m5a97 r2 or evo version will fit on your needs, and this board is overclock able well..
