Your temps are normal...out of curiosity, do you know how many fps you are getting in crysis3 with that gpu? If so try ultimate settings and see what they are...Please?
Everything on max the AA is on FXAA, not MSAA or any others.. not sure what the difference is. I have cpu overclocked to 4.6Ghz as well, cpu temp never goes above 45 with my corsair h100i. I think all my temps are good, my motherboard is 30-36c not sure if this is good for a motherboard. Don't know much about motherboards temps..
