Hello. I just bought sapphire 7870 card. Everytime I play a game (GTA V, Battlefield 4 etc. ) i got a crash. It depends on time, in bf4 its about 40 minutes, in gta V in about 1h. Everything works on maximum settings mostly on 40fps+ There's always a directX error (every box says that when the game crashes). The card isn't overheating (at least i think it isn't, because it reaches max 80°C). I have no idea what to do. I have the latest GPU drivers.
i3 4170 @3.7
Ram 8gb DDR3 1333MHz (already tested with memtest, no errors)
