I ran a FurMark Burning test and the temp. reached 85c degree
and ran Metro last light benchmark and got 30 FPS Avg while others got 50 FPS
ran 3dMark "SkyDiver" benchmark and got score of 18k while others got 22k~25k

My build is
gigabyte 970a-ds3p
8gb kingstone Fury
r9 280x gigabyte triangle fan
FX-8350 unlocked\

P.S. none of the CPU isn't over clocked while the GPU is factory overclocked to 1100 MHz

thanks in advance
