What a stupid discussion! the 730M is actually great for playing most games.
And one of the best features of the 1440p resolution for games is that you can combine 4 pixels into one, ending up with a 720p display free of any scaling artifacts, which the 730M GPU will drive brilliantly.
Any MMORPG will run great on this machine and look way better than on a quartered 1080p display, which would reduce it to 540p, which is too low to look good.
As for those dullards saying "Ultrabooks aren't made for gaming": wake up, we aren't living in a static universe, things keep developing...
