It should actually be enough. I ran the wattage numbers when I built my rig and opted for an 850w PSU just so I'd have some room for more devices and not have to worry about efficiency decay of the PSU over time, but 750w would have been enough. The temps this game can cause are really ****ing weird, though. AC Unity doesn't cause my cards to run this hot, so I think I may try rolling back to the .12's and see if that helps.
I run the game first with previous drivers just to check,then I update to latest driver,less issues about lockups I had but still there are few at random gameplaying times. No performance drop or gain,tempratures are same(hottest I've seen comparing to any other game, max I've seen 72 but I haven't play much yet). Maybe it will be better,try and check.
Entry level Corsiar PSU suck major. Personally, Id never run any dual cards on less then a 800w premium psu anyways.
bro with ur 970 u should hit easily the 60 fps mark, we are talking about a 350$ card... that's weird if it doesnt hit the 60 fps.
in my pc setup i can reach around 60 fps all max 1080p. probably he cant hu? and i use VSYNC on with 60 fps cap. mostly 54 fps but i can hit 60 too.
