I have the same issues you speak of. I crashed in overwatch, titanfall2 and world of Warcraft. I have even underclock the core and memory clock settings and set the power target to +10 and fan at 50% upon start up. Actually the reason I'm here is I'm thinking maybe the card is defective, so I'm doing thorough research to see if its the card or the product line before I return it to microcenter and get something else.
I'm having very similar issues out of the same card, 4GB edition. I've had mine since the beginning of the month, and it didn't seem to have any problems, but the last few days, it's been crashing out. I've rolled back drivers and used DDU to completely remove and then fresh reinstall them. I'm running the card at a full 20% higher power target. I came from an R9 290, a much more power intensive card, and never had problems. I think I'm just going to take it back to the store, unless someone has a solution that I've not tried.

I'm having the same issues. I also thought it was a PSU issue and upgraded to a corsair 750w bronze with no difference.
also running win10x64
I've sent an email to gigabyte but they have yet to respond. I'm planning on calling newegg to get them to send me a new card
I exchanged the cards at best buy and I have not crashed since, so I guess the card I got was a bad one.
