Its really easy to hit the power limit.
That EVGA card only allows +37mv and clocks changing between 1430 and 1410 is hardly throttling. The hour I played on BF4 with my MSI the GPU clock stayed at 1506 MHz consistently. I'm going to see if 1600mhz is game stable as its bench stable. Will report back if it throttles.
