difference between the two
armor core clock 980mhz gaming 1000mhz
armor video ports 1 HDMI, 1 DP, 2 DL-DVI-I gaming 1 DP, 1 DL-DVI-I, 1 DL-DVI-D
Cooler on the gaming card is slightly better then the armor.
Unless you need the HDMI port i would go with the gamer card. Slightly better base core speed and better cooler.
