Played Assassins Creed 3. Performance was relatively rather low. Had to make all settings on normal (as opposed to High or Ultra) - otherwise if on higher settings significant lag or graphics issues, especially in daylight scenes. Overclocking did not seem to help at all. Lowering resolution did nothing to increase performance. Using CCC 12.10. Haven't tested any other games. (Hard to find time to play games - this was the first time playing a game since I built the system 4 months ago!!) However it was still awesome to play in HD 1080p on a 50" screen! And on normal graphics it was still HD and looked rather awesome. UPDATE: Just tested on the 24" monitor, same graphics issues on Very High (ultra) mode for AC3.
