It lacks integrated graphics so by itself no it cannot. With even a modest gpu ($50 to $300), it should easily play HD videos and the more you spend on the gpu the more games it will be able to play. Unfortunately this processor is no longer considered to be very strong so if you spend too much on a gpu it may be held back by this cpu. I would focus on spending less and allowing yourself to play HD videos and not really get too excited about high end games. If you put a ceiling budget of about $150 and get something like a GTX 750 Ti you should be able to both watch HD and game ok. Again, don't expect to play the most graphically intensive titles without some bottlenecking by this processor but again, with the right gpu you can play...
