So I got this red devil ultimate, only had a bit of time to play with it. So far I tested with furmark: 2.5GHz 1150mv (1060mv read hwinfo) 320W read (390W measured at wall card only) 2.45GHz 1130mv (1009mv read) 275W read 2.4GHz 1120mv (930mv read) 245W read I'm happy with the 2.4GHz, testing in forza 5 card sits at 200-210W, 55C/67C (gpu/junction) Witcher loads the card basically almost like furmark, 235W 60/75C Now my question is, I've seen the game stuttering from time to time, especially in witcher more often and looking at the graphs I can see the card going to 0% utilization for like half a second when it happens. I doesn't reach the TGP/TDP (350W set in software), basically goes to 200-230W depending on game. Temperatures are OK. There is no issue with power delivery. Any thoughts?
