So I am using Sapphire HD7970 @ 1100/1500, i-5 @ 4.2ghz and have been since day one. In the last week, every third or fourth multiplayer game, I notice the framerate to start to falter... like, 60+fps---5fps-----60fps and my GPU usage suddenly drops to nothing, clocks go into idle mode (300mhz core) then to zero usage, and the game crashes. Temps are high 50s, no problem there... this only happens with Crysis 3 and has only started happening recently. Anyone else have a simliar problem?
