Hi !
Same Situation on my Asrock P67 Extreme6 - I7 2600k - AMD 6970 - Corsair CMX8GX3M2A1600C9 - G15 Refresh - Corsair F40 in Raid0 - SAMSUNG HD502HJ (S20BJ9CZ520529) in Raid0
But not only in gaming, i'am also experiencing lags in common pc usage, specially shown by laggs during mouse movement. As soon i stop AIDA64, the problem is gone.
