The MB is not meant for gamers, at least not the latest 3D-type games. It may run them, but not at the highest quality settings. And you cannot upgrade the video ram.
About the plug, I'm guessing you get the two-round prong plug. But whatever plug you get it's easy enough to get a converter which you may have to anyway. Most power sockets here in the UAE are the UK type with two/three square prongs.
