If yours keeps doing it prob just have to rma.. maybe try diff drivers?
Thanks for your reply.
I tried a bunch of different drivers (now i'm on the latest beta drivers) and i still encounter in this issue. And this issue is unrelated with games: i face these freezes in GRID 2, BioShock Infinite, Battlefield 3, XCOM, The Witcher 2, even DOTA 2 (that is very low in hardware requirements).
In these pages
of this thread it came out that was a driver issue, or a problem related with power management, but i think that no solution was come out.
I really don't want to RMA this card (it was very cheap and, aside from the freezes, it has very good performance), but if there's no way to solve it i will consider that.
