I'm running 2 x 7870's with no issues on any game with the exception of GTA V. Running as a single card it runs perfectly fine so no complaints there. But I have to turn off crossfire to play is for when turned on, it is impossible to play. It freezes, runs extremely sluggish, graphical glitches occur and just plain unplayable. All these even though the graphics settings are exactly the same. I'm hoping someone may be able to shed some light on this and curious how many others may have crossfire issues with GTA V also.
